Description
Technical Field
The invention relates to the field of medical instruments, in particular to a method for determining emission parameters of ultrasonic equipment and a probe.
Background
When an operator uses the wireless probe to perform clinical ultrasonic diagnosis, an examination mode suitable for the body type and the tissue, such as a liver mode of the abdomen, is selected according to the body type and the tissue of a part to be diagnosed of a detected body.
The ultrasound system scans with default transmit parameters (including transmit voltage values, pulse frequency) for the tissue. However, the same tissue of different human bodies and different positions and sections of the same tissue of the same individual may have larger differences, and the use of a set of default emission parameters cannot meet the image requirements of the above situations.
The operator often needs to repeatedly adjust the transmitting voltage value and move the section of the probe, and the optimal image effect is selected according to visual judgment. For example, the default emission voltage value is only suitable for scanning normal tissues, and for variant tissues, such as hardened liver and fibrotic liver, the emission voltage value needs to be reduced and fine-tuned to obtain better image contrast and identify the variant part. The above process of repeatedly adjusting parameters and visually determining usually consumes much time.
The existing scheme is as follows: the wireless probe scans images by using a default fixed high-voltage value (transmitting voltage value) of a certain tissue, an operator needs to judge according to a real-time image and manually and continuously adjust the transmitting voltage value, and the satisfactory image effect can be achieved only by spending a long time.
There are disadvantages in that: firstly, human eyes are needed to judge whether an image is good or bad, and the optimal image cannot be found necessarily depending on the experience and the technical level of an operator. Second, less experienced or non-sonographed operators may spend a long time finding a satisfactory image and corresponding voltage value. And thirdly, the default transmitting voltage value is generally higher, and the sound power output by the wireless probe for a long time is also higher, so that the safety of the sound power of the human body is not facilitated. And fourthly, because the wireless probe has limited duration, individuals which can be diagnosed can be reduced by adopting a default voltage value for checking.
Therefore, the working efficiency of the existing wireless probe needs to be improved, and the power consumption needs to be reduced.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
As shown in fig. 1, the present invention provides an ultrasound apparatus including a probe 10, a controller 20, a transmission circuit 30, a reception circuit 40, and a transmission power supply 50.
The probe 10 includes a transducer (not shown) comprising a plurality of array elements arranged in an array. The array elements are used to transmit ultrasonic waves based on an excitation electrical signal (pulse signal) output from the transmission circuit 30 or convert received ultrasonic waves into an electrical signal. Each array element can thus be used to convert the electrical pulse signal and the ultrasound wave into one another, so that the ultrasound wave is transmitted to the target tissue and the echo of the ultrasound wave reflected back through the tissue is also received.
The transmission power supply 50 is used to power the transmission circuit 30. The output voltage is finally supplied to the array element of the probe 10 through the transmitting circuit 30 to provide electric energy for the array element to transmit ultrasonic waves, so the output voltage is also called transmitting voltage. The transmitting power source 50 may be a programmable power source, so the output voltage is also called a programmable voltage, and the programmable power source is adopted to adjust the output voltage conveniently.
The transmitting circuit 30 is used for converting the voltage output by the transmitting power source 50 into a pulse signal (e.g., an electric pulse, such as a positive pulse or a negative pulse) and then exciting the array elements of the probe 10 to transmit ultrasonic waves to the target tissue according to the control of the controller 20.
The receiving circuit 40 is configured to receive the ultrasound echo returned from the target tissue through the array element of the probe 10 to obtain an ultrasound echo signal, and may also process the ultrasound echo signal. The receive circuitry 40 may include one or more amplifiers, analog-to-digital converters (ADCs), and the like. For example, the receiving circuit 40 includes an isolation chip and a front-end chip, the ultrasound echo is isolated by the isolation chip and then input to the front-end chip, and the front-end chip converts an ultrasound echo signal (analog signal) into a digital signal, so that the subsequent controller 20 processes the digital signal to obtain a frame of ultrasound B image of the target tissue.
The controller 20 may include a beam synthesis module, an IQ demodulation module, and a processor.
The beam forming module is connected to the receiving circuit 40 for performing beam forming processing such as corresponding delay and weighted summation on the digital echo signal, because distances from the ultrasonic receiving point in the target tissue to the receiving array elements are different, channel data of the same receiving point output by different receiving array elements have delay difference, delay processing is required, phases are aligned, and weighted summation is performed on different channel data of the same receiving point to obtain ultrasonic image data after beam forming, and the ultrasonic image data output by the beam forming module is also referred to as radio frequency data (RF data). The beam synthesis module outputs the radio frequency data to the IQ demodulation module. In some embodiments, the ultrasound device further includes a memory, and the beam forming module may also output the radio frequency data to the memory for buffering or saving, or directly output the radio frequency data to the processor for image processing.
The beamforming module may perform the above functions in hardware, firmware or software. The beam forming module may be integrated in the processor or may be separately disposed, which is not limited in the present invention.
The IQ demodulation module removes a signal carrier by IQ demodulation, extracts tissue structure information included in the signal, and performs filtering to remove noise, and the signal obtained at this time is referred to as a baseband signal (IQ data pair). And the IQ demodulation module outputs the IQ data pair to a processor for image processing. In some embodiments, the IQ demodulation module further buffers or saves the IQ data pair output to the memory, so that the processor reads the data from the memory for subsequent image processing.
The IQ demodulation module can also perform the above functions in hardware, firmware or software. Similarly, the IQ demodulation module may be integrated into the processor or may be separately disposed, which is not limited in the present invention.
The processor is used for a central controller Circuit (CPU), one or more microprocessors, a graphics controller circuit (GPU) or any other electronic components configured to process input data according to specific logic instructions, which may control peripheral electronic components according to the input instructions or predetermined instructions, or perform data reading and/or saving on a memory, or may process input data by executing a program in the memory, for example, perform one or more processing operations on acquired ultrasound data according to one or more operating modes, the processing operations including, but not limited to, adjusting or defining the form of ultrasound waves emitted by the probe 10, generating various image frames for display on a subsequent display, or adjusting or defining the content and form of display on a display, or adjusting one or more image display settings (e.g., ultrasound images, graphics controller circuits (GPUs) displayed on a display, Interface components, locating regions of interest).
The acquired ultrasound data may be processed by the processor in real time during the scan as the echo signals are received, or may be temporarily stored in memory and processed in near real time in an online or offline operation.
The processor is also configured to process the ultrasound data to generate a gray scale image of the signal intensity changes over the scan range that reflects the anatomical structure inside the tissue, referred to as a B-image.
Although the prior art ultrasound device has a default transmitting voltage value to excite the probe to transmit the ultrasound wave during scanning, the same tissue of different human bodies, different positions and sections of the same tissue of the same individual may have large differences, so that the doctor usually adjusts the transmitting voltage and finds a suitable value. The present invention, however, provides an ultrasound device in which the controller 20 can automatically determine the transmit voltage appropriate for the current slice without manual adjustment by the physician. The controller 20 may control the transmit power supply 50 to maintain the transmit voltage of the probe at a determined value, or may control the transmit circuit 30, as described in detail below in connection with two embodiments.
In an embodiment, as shown in fig. 2, the controller 20 is configured to obtain a current operating mode, determine a target voltage value of the transmitting power supply 50 if the current operating mode is a voltage calibration mode, and start a normal scan, for example, control the transmitting power supply 50 to continuously output a voltage of the target voltage value to power the transmitting circuit 30. It is convenient that the user can freely select the turn-on and turn-off voltage calibration mode, that is, the controller 20 can turn on or turn off the voltage calibration mode based on the user's operation.
The controller 20 determines the target voltage value of the transmitting power supply 50, as shown in fig. 3, including the steps of:
The ultrasonic equipment provided by the invention can be various types of medical ultrasonic imaging equipment, such as a desktop ultrasonic imaging equipment, a portable ultrasonic imaging equipment and a handheld ultrasonic probe. The present embodiment is described by taking a hand-held ultrasound probe as an example.
Specifically, in steps 11 and 12 of this embodiment, after the user places the handheld ultrasonic probe on the body surface and selects an examination mode of a certain tissue, the controller 20 controls the transmitting power supply 50 to start supplying power to the transmitting circuit 30 with a default transmitting voltage (initial voltage value) of the tissue, the transmitting circuit 30 excites the array element of the probe 10 to transmit ultrasonic waves for scanning, receives an ultrasonic echo signal, and the controller 20 generates a frame of first ultrasonic images corresponding to the initial voltage value.
Next, the controller 20 controls the voltage source according to the initial voltage value V1Obtaining a second voltage value V by using the preset voltage difference DeltaV as the step pitch2＝V1-M. The preset voltage difference Δ V can be set according to the requirement, for example, the preset voltage difference Δ V is an initial voltage value V 12%, 3%, 5%, etc., in this example, Δ V ═ V1The expression "X3" will be described as an example. The smaller Δ V, the more suitable the target voltage value to be determined subsequently, but the time taken is also relatively long. The controller 20 controls the transmitting power supply 50 to start at the second voltage value V2The transmitting circuit 30 is powered so as to excite the array element of the probe 10 to transmit ultrasonic waves for scanning, receive ultrasonic echo signals, and generate a second voltage value V by the controller 202The corresponding frame of the first ultrasonic image.
The controller 20 is controlled according to the second voltage value V2Obtaining a third voltage value V by using the preset voltage difference delta V as a step pitch3＝V2-M. The controller 20 controls the transmitting power supply 50 to start at the third voltage value V3The transmitting circuit 30 is powered, so that the array elements of the excitation probe 10 transmit ultrasonic waves for scanning, receive ultrasonic echo signals and are controlled by the control unitThe controller 20 generates a third voltage value V3The corresponding frame of the first ultrasonic image.
……
The controller 20 is controlled according to the (n-1) th voltage value Vn-1Obtaining the nth voltage value V by using the preset voltage difference delta V as the step pitchn＝Vn-1-M. The controller 20 controls the transmitting power supply 50 to start with the nth voltage value VnThe transmitting circuit 30 is powered so as to excite the array element of the probe 10 to transmit ultrasonic waves for scanning, receive ultrasonic echo signals and generate an nth voltage value V by the controller 20nThe corresponding frame of the first ultrasonic image.
n is an integer greater than 1, and the above process may be ended by defining a value of n, where n may be set according to a user's requirement, for example, n is an integer from 6 to 20, and this embodiment is described by taking n ═ 11 as an example, that is, the controller 20 controls the voltage value traversed by the transmitting power supply 50 to be from 100% V1Reduced to 70% V1And 11 frames of B-mode images (first ultrasound images) of different contrasts are generated.
And step 13, the controller 20 screens a frame of first ultrasonic image from each generated first ultrasonic image according to preset image screening conditions, wherein a voltage value corresponding to the screened first ultrasonic image is a target voltage value. For example, the controller 20 analyzes the quality of each first ultrasound image and selects the first ultrasound image of the frame with the highest quality, in other words, the image screening condition is the highest image quality. The method comprises the steps of establishing a database in advance, wherein a plurality of ultrasonic images are stored in the database, each ultrasonic image is marked with a corresponding quality score, the quality of the quality score reflects the quality of the image, training a deep learning model by using the ultrasonic images in the database, sequentially inputting the first ultrasonic images into the model after the model is trained, outputting the corresponding quality scores by the model, and reflecting the quality of the image, so that the first ultrasonic image with the highest quality can be selected according to the quality scores. In addition to the image quality, the first ultrasound image may be selected in consideration of energy saving, for example, the controller 20 analyzes the quality of each first ultrasound image and selects a frame of the first ultrasound image according to the quality of the first ultrasound image and the voltage value corresponding thereto. Specifically, the quality scores of the first ultrasonic images can be obtained by the method, so that the first ultrasonic images are sorted from high to low according to the quality scores, and if a plurality of (two or more) first ultrasonic images with the quality scores having a difference smaller than a preset difference exist, the first ultrasonic images with small voltage values are sorted to the front; after sorting in this way, the voltage value corresponding to the first ultrasound image sorted first is taken as the target voltage value. Of course, in the first ultrasound image whose mass fraction exceeds the preset fraction (exceeding the preset fraction indicates that the mass has reached the standard), the lowest voltage value of the corresponding voltage values may be used as the target voltage value. There may be other ways to compromise image quality and reduce power consumption, not to mention here.
Taking the convex array probe for examining the abdominal tissues as an example, the frame rate per second is 20 frames, each frame time is 50ms, and the scanning time of 11 frames of images is 550 ms. Taking the phased array probe for examining cardiac tissue as an example, the frame rate per second is 40 frames, each frame time is 25ms, and the scanning time of 11 frames of images is 275 ms. Therefore, after scanning of a certain tissue section image, the ultrasonic equipment only uses 275-550 ms to traverse and select the high voltage value, so that an image with the optimal quality can be intelligently obtained, and the target voltage value can be determined as long as 275-550 ms is used. In the prior art, an operator needs to adjust the transmitting voltage value continuously and manually, and takes a long time, but the method automatically selects the optimal image effect to determine the target voltage value, thereby greatly shortening the adjusting time and improving the tissue examination efficiency. And the selected target voltage value is often lower than a default value (initial voltage value), so that the acoustic power and the working electric power of the ultrasonic equipment are reduced, the acoustic power safety of a human body is ensured, and the endurance time is prolonged.
In some embodiments, step 13 may also be performed by an external device, such as a server, for example, the ultrasound device further includes a communication module 60, the controller 20 transmits each first ultrasound image to the server (e.g., a cloud-end server) through the communication module 60, the server screens out a frame of first ultrasound images from each generated first ultrasound image according to a preset image screening condition, the specific process is the same as that of step 13, which is not described herein again, and then the server feeds back the screened first ultrasound images to the controller 20, and the controller 20 determines the voltage value corresponding to the screened first ultrasound images as the target voltage value.
In the embodiment shown in fig. 2, after the target voltage value is obtained, the target voltage value is used as the transmission voltage value of the probe 10, and the scanning is started (step 2). That is, the controller 20 controls the transmitting power supply 50 to continuously output the voltage of the target voltage value to the transmitting circuit 30, the transmitting circuit 30 converts the voltage into a pulse signal and outputs the pulse signal to the probe 10, so as to excite the array element of the probe 10 to transmit the ultrasonic wave, the probe 10 converts the echo of the ultrasonic wave into an analog echo signal, the receiving circuit 40 converts the analog echo signal into a digital echo signal, and the controller 20 processes the digital echo signal and generates the ultrasonic image. The formal scanning adopts the target voltage, and the value of the target voltage does not exceed the initial voltage value, so that the image quality can be well ensured, and the power consumption can be reduced.
If the current operating mode is the mapping mode, the controller 20 obtains the target voltage value determined by the voltage calibration mode, and starts to scan the map: the transmitting power supply 50 is controlled to continuously output the voltage of the target voltage value to the transmitting circuit 30, the transmitting circuit 30 converts the voltage into a pulse signal and outputs the pulse signal to the probe 10, so as to excite the array element of the probe 10 to transmit ultrasonic waves, the probe 10 converts the echo of the ultrasonic waves into an analog echo signal, the receiving circuit 40 converts the analog echo signal into a digital echo signal, and the controller 20 processes the digital echo signal and generates an ultrasonic image.
Both desktop ultrasound imaging devices and portable ultrasound imaging devices typically have a display through which the ultrasound images generated by the controller 20 may be displayed. While the hand-held ultrasound probe in this embodiment is small in size and cannot be mounted with a large-sized display, it generally has a communication module 60 for communicating with an external device, as shown in fig. 6, the controller 20 is connected with the display terminal 70 through the communication module 60, so as to output the generated ultrasound image to the display terminal 70 for display. The communication module 60 may be in wired connection with the display terminal 70, for example, the communication module 60 is a communication interface and is in wired connection with the display terminal 70 through a cable. The communication module 60 may also be wirelessly connected to the display terminal 70, for example, the communication module 60 is an existing wireless communication module (such as a bluetooth module, a WIFI module, a 4G/5G communication module, etc.), and the embodiment is described by taking wireless connection as an example, that is, in the embodiment, the ultrasound device is a wireless ultrasound probe.
In the embodiment shown in fig. 2, the normal scan can be started after the target voltage value is obtained, however, the transmission parameters of the ultrasound apparatus include the frequency of the pulse signal in addition to the transmission voltage value, so in the embodiment shown in fig. 4, before the normal scan is started, the frequency of the pulse signal may be determined, that is, after step 1, step 1.0 is further included, where, as shown in fig. 5, step 1.0 includes the following steps:
step 1.1, the controller 20 controls the transmitting power supply 50 to operate continuously, that is, the transmitting power supply 50 continuously outputs a voltage with a fixed voltage value to the transmitting circuit 30, where the fixed voltage value may be a target voltage value. The controller 20 controls the transmitting circuit 30 to sequentially convert the voltage output by the transmitting power supply 50 into a plurality of pulse signals with different frequencies and output the pulse signals to the array elements of the probe 10, so as to sequentially excite the array elements of the probe 10 to transmit ultrasonic waves, and controls the array elements of the probe 10 to receive echo signals of the ultrasonic waves through the receiving circuit 40. Generally, the frequency F of a pulse signal is preset in the ultrasonic equipment, so that the frequency F can be increased or decreased to obtain a plurality of different frequencies. For example, based on frequency F, with 0.5MHz as the step size, 5 different sets of frequencies are obtained: F. f +0.5MHz, F +1MHz, F-0.5MHz and F-1 MHz.
Step 1.2, the controller 20 generates a corresponding second ultrasound image according to the echo signal of the ultrasound wave. That is, a pulse signal of one frequency excites the array elements of the probe 10, and at least one frame of the second ultrasound image can be obtained. A plurality of pulse signals with different frequencies are correspondingly obtained to obtain a plurality of second ultrasonic images. The specific process is similar to step 12, and is not described herein again.
Step 1.3, the controller 20 screens a frame of second ultrasonic image from the generated second ultrasonic images according to preset image screening conditions, and the frequency corresponding to the screened second ultrasonic image is the target frequency. Similarly, the controller 20 may analyze the quality of each second ultrasound image and select the second ultrasound image with the highest quality frame, in other words, the image screening condition is the highest image quality. The specific screening process is the same as step 13, and is not described herein.
In this embodiment, after obtaining the optimal target voltage value and the optimal pulse signal target frequency, the ultrasound device starts to scan the map formally with the target voltage value and the target frequency (step 2). That is, the controller 20 controls the transmitting power supply 50 to continuously output the voltage of the target voltage value to the transmitting circuit 30, the transmitting circuit 30 converts the voltage into a pulse signal of the target frequency and outputs the pulse signal to the probe 10, so as to excite the array element of the probe 10 to transmit the ultrasonic wave, the probe 10 converts the echo of the ultrasonic wave into an analog echo signal, the receiving circuit 40 converts the analog echo signal into a digital echo signal, and the controller 20 processes the digital echo signal to generate the ultrasonic image.
If the current operating mode is the mapping mode, the controller 20 obtains the target voltage value and the target frequency determined by the voltage calibration mode, and starts to scan the map: the transmitting power supply 50 is controlled to continuously output the voltage of the target voltage value to the transmitting circuit 30, the transmitting circuit 30 converts the voltage into a pulse signal of the target frequency and outputs the pulse signal to the probe 10, so as to excite the array element of the probe 10 to transmit ultrasonic waves, the probe 10 converts the echo of the ultrasonic waves into an analog echo signal, the receiving circuit 40 converts the analog echo signal into a digital echo signal, and the controller 20 processes the digital echo signal and generates an ultrasonic image.
Of course, in some embodiments, step 1.0 may be performed first, and then step 1 is performed, and the specific process is the same as above and is not described in detail.
In the prior art, some methods automatically adjust the transmitting voltage value in real time and continuously compare the transmitting voltage value with a standard ultrasonic image until the image comparison result falls within a preset error tolerance range. It has the following disadvantages: 1. the method needs to change the voltage value continuously in real time, so that the contrast difference of each frame of image exists, the stable image quality does not exist, and the clinical judgment of operators is influenced. 2. The real-time image is compared and closed with the standard ultrasonic image, but the standard ultrasonic image cannot represent the condition of optimal image quality, different physique and different tissues, and the image obtained after adjustment is not optimal for the lesion tissues. The method provided by the invention comprises the following steps: the image with the optimal quality is intelligently selected from the multi-frame images obtained based on different voltage values and/or different pulse signal frequencies, and the quality of the image obtained by voltage adjustment and/or frequency adjustment each time can be ensured to be optimal.
After obtaining the target voltage value and/or the target frequency, the controller 20 may be further configured to obtain a patient identifier of the current patient and a current scanning section, and associate the target voltage value and/or the target frequency with the patient identifier and the current scanning section; when the subsequent patient scans the section again, the transmitting power supply 50 is directly controlled to continuously output the voltage of the target voltage value, and the transmitting circuit 30 is controlled to convert the voltage output by the transmitting power supply 50 into the pulse signal of the target frequency and output the pulse signal to the probe 10. Thus, the step of determining the target voltage value and/or the target frequency can be omitted, and the method is quicker.
In step 1 above, the controller 20 also records: and generating the time domain characteristics or the frequency domain characteristics of the echo signals received by each channel (array element) of the probe in the echo signals of the screened first ultrasonic image. That is, in step 1, the time domain characteristics or the frequency domain characteristics of the echo signals received by the respective channels of the probe are recorded in the echo signals corresponding to the first ultrasound image with the best image quality. The time domain characteristic or the frequency domain characteristic may be one of amplitude, bandwidth, phase and frequency spectrum, and the present embodiment is illustrated with amplitude as an example.
During the scanning, the controller 20 also detects whether the probe 10 moves in real time, and if so, the target voltage value of the transmitting power supply 50 is determined again, i.e. the step 1 is returned to. Under the same transmitting voltage, the probe scans tissues at the same position front and back, the time domain characteristics and the frequency domain characteristics of echo signals received front and back of a channel are smaller, and if the difference is too large, the probe moves, so that the front and back received signals have larger difference. Therefore, during the scanning, the controller 20 can detect the time domain characteristics or the frequency domain characteristics of the echo signals received by each channel of the probe 10 in real time; comparing the detected time domain characteristic or frequency domain characteristic with the recorded time domain characteristic or frequency domain characteristic, and determining that the probe 10 has moved when the difference between the detected time domain characteristic or frequency domain characteristic and the recorded time domain characteristic or frequency domain characteristic exceeds a preset threshold. Taking the amplitude as an example, it is assumed that, in the echo signals corresponding to the screened first ultrasound image recorded in step 1, the amplitudes of the echo signals received by the M channels of the probe 10 are recorded; during the main scanning, each time the M channels of the probe 10 receive an echo signal, the controller 20 compares the amplitudes of the echo signals received by the M channels with the recorded M amplitudes in sequence, and if the difference between the two amplitudes exceeds a preset threshold, it is determined that the probe 10 has moved. The preset threshold may be set according to the user's needs, for example, it may be 20% of the recorded amplitude.
The controller 20 may also detect whether the currently scanned section is changed in real time, and if so, re-determine the target voltage value of the transmitting power supply 50, i.e. return to step 1. In some automatic workflows of the ultrasound apparatus, generally, a section is selected first, then a scanogram is started, a user completes the scanogram of one section, and then after starting the scanogram of another section, the probe 10 certainly needs to move the position, so that the controller 20 determines the target voltage value and the target frequency again after detecting that the user changes the section, thereby better adapting to the scanogram of the current section and improving the imaging quality.
Therefore, the ultrasonic equipment provided by the invention only needs to perform voltage traversal when a doctor moves the position of the probe and changes the section; if the position of the probe and the section are not changed, the system always keeps a constant and optimal transmitting voltage for image scanning. Therefore, the image effect and the image contrast obtained by the wireless probe are stable corresponding to each tissue section, and the clinical diagnosis of an operator is facilitated.
In some embodiments, as shown in fig. 7-9, the controller 20 may also control the transmit voltage by controlling the transmit circuit 30. The difference between this embodiment and the above embodiment is only step 1, which is described below.
The ultrasound device may perform an ultrasound scan of the target tissue using the procedure shown in fig. 7, or using the procedure shown in fig. 9. In step 1', the controller 20 determines the target voltage value of the pulse signal, and may adopt the steps shown in fig. 8:
step 11', the controller 20 controls the transmitting power source 50 to work, controls the transmitting circuit 30 to sequentially convert the voltage output by the transmitting power source 50 into a plurality of pulse signals with different voltage values and output the pulse signals to the probe 10, so as to excite the array elements of the probe 10 to transmit ultrasonic waves, and controls the array elements of the probe 10 to receive echo signals of the ultrasonic waves through the receiving circuit 40. In short, this step differs from the above step 11 in that: this step is realized by controlling the transmitting circuit 30 to output a plurality of different transmitting voltages, and the step 11 is realized by controlling the transmitting power supply 50. Other processes are the same and are not described herein.
Step 12', the controller 20 generates a corresponding first ultrasound image according to the echo signal of the ultrasound wave. The detailed process is the same as step 12, and is not described herein.
Step 13', the controller 20 screens out a frame of first ultrasonic image from each generated first ultrasonic image according to a preset image screening condition, and a voltage value corresponding to the screened first ultrasonic image is a target voltage value. The detailed process is the same as step 13, and is not described herein.
