(First embodiment)
A medical image processing apparatus according to a first embodiment will be described with reference to the block diagram of FIG.
The medical image processing apparatus 1 includes a storage circuit 101, a processing circuit 110, and a display circuit 105. Signal exchange is performed via the bus 10.

  The storage circuit 101 is a memory, for example, and stores image data. Here, the image data assumes a DICOM (digital imaging and communication in medicine) standard data format, and includes a medical image, incidental information attached to the medical image, and a region-of-interest image (second medical image) described later. Including. The incidental information includes information regarding image matrix information and reconstruction matrix information. The image matrix information indicates the size of the image matrix of the medical image. The reconstruction matrix information indicates image matrix information of an image (original image or first medical image) that is a basis of the region-of-interest image. When the region-of-interest image is generated by cutting out multiple times step by step, the reconstruction matrix information is large. The image matrix information of the medical image used as a book is shown. In the case of an original image, the image matrix information and the reconstruction matrix information are equal.

The processing circuit 110 is, for example, a processor, and executes the generation function 102, the incidental function 103, and the display control function 104.
The generation function 102 refers to image data stored in the storage circuit 101, cuts out a region of interest from the original image, and generates a region of interest image.

  The supplementary function 103 appends supplementary information attached to the original image to the region of interest image generated by the generation function 102. Here, at least information related to the reconstruction matrix information is attached.

  The display control function 104 displays an interface screen on the display circuit 105 and controls display of medical images, incidental information, and region-of-interest images. The display control function 104 controls the display mode of the medical image, the incidental information, and the region of interest image in accordance with an instruction from the user. The display control function 104 may display a medical image, incidental information, and a region of interest image on an external display device connected via a network or the like.

  The display circuit 105 is a display, for example, and displays a medical image, incidental information, and a region of interest image.

  An operation example of the medical image processing apparatus 1 according to the first embodiment will be described with reference to the flowchart of FIG.

In step S <b> 201, the display control function 104 displays a selection screen for selecting a medical image on the display circuit 105. The selection screen displays at least a medical image and incidental information.
In step S <b> 202, the user selects a medical image that the user wants to perform the clipping process, and the generation function 102 acquires the selection result.
In step S <b> 203, the generation function 102 performs a cut-out process from the original image using the medical image selected by the user as an original image according to the selection result, and generates a region-of-interest image.

In step S204, the auxiliary function 103 adds the image matrix information of the region of interest image and the reconstruction matrix information of the original image to the region of interest image. Note that the image matrix information of the original image may also be attached.
In step S205, the storage circuit 101 stores the region-of-interest image, the attached image matrix information, and reconstruction matrix information.
In step S206, when the display control function 104 displays the region of interest image, the image matrix information of the region of interest image and the reconstruction matrix information attached in step S203 are displayed together.

Next, an example of the selection screen displayed on the display circuit 105 will be described with reference to FIG.
FIG. 3 is an interface screen related to a medical image selection screen. Each of the display windows includes a study information display window 301, a series information display window 302, and an image information display window 303. In the image information display window 303, image matrix information 304 and reconstruction matrix information 305 are displayed in association with each other in addition to medical images, information such as scan time, identification number, and start / end positions.

  When the region-of-interest image is generated, it is stored in the storage circuit 101 as series information different from the original image. Specifically, the series information of the region-of-interest image is stored as another series information immediately below the series information regarding the original image.

Next, details of the cut-out process in step S203 will be described with reference to FIG.
FIG. 4 is an interface screen related to the clipping process. The user moves the cutout window 402 superimposed on the display of the medical image 401 by a cursor or mouse drag operation or the like, and determines the region of interest within the cutout window 402. Thereby, the region-of-interest image is cut out. Since the size of the image matrix of the region-of-interest image is assumed to be 512 × 512 pixels, the clipping window 402 has a fixed size of 512 × 512 pixels. Specifically, when the original image is 1024 × 1024 pixels, a quarter size of the original image corresponds to 512 × 512 pixels.

Next, a display example of a medical image will be described with reference to FIGS.
FIG. 5 is an example of an image display interface screen, and an image selection window 502 (image selector) is displayed superimposed on the display of the medical image 501. The image selection window 502 displays series information 503 (series comments) and a thumbnail 504 of a medical image for each series. In the series information 503, information of the image matrix information 505 is displayed. In the example of FIG. 5, the numerical value of the image matrix information is displayed as a label (batch display). The label display format (color, character size, etc.) may be changed according to the image matrix information.

  When the clipping process is performed, the series information and thumbnail of the region-of-interest image generated as another series are displayed immediately below the series information and thumbnail of the original image. In the example of FIG. 5, it is assumed that a region of interest image is generated by cutting out a medical image having series information (1024 × 1024 pixels) at the top of the image selection window 502 and a corresponding thumbnail as an original image. In this case, the series information (512 × 512 pixels) and the corresponding thumbnail are displayed second immediately below the original image.

Next, an example in which the original image and the region-of-interest image are displayed in parallel is shown in FIG.
The reconstruction matrix information 603 attached to the original image 601 is displayed in the display area of the original image 601. Similarly, the reconstruction matrix information 604 attached to the region of interest image 602 is displayed in the display area of the region of interest image 602.

  By displaying the supplementary information of the reconstruction matrix in this way, it is possible to easily determine whether a medical image of a different image matrix is an original image or a region-of-interest image cut out from the original image.

  For example, in the example of FIG. 6, when viewing the image display screen, the image matrix information of the original image 601 is 1024 × 1024 pixels, and the image matrix information of the region-of-interest image 602 is 512 × 512 pixels. On the other hand, the reconstruction matrix information is 1024 × 1024 pixels. Thereby, it can be understood at a glance that the region-of-interest image 602 is a medical image cut out from a medical image of 1024 × 1024 pixels, not the original image matrix size obtained with 512 × 512 pixels. . Further, the resolution of the extracted region-of-interest image can be predicted from the reconstruction matrix information.

An image indicating which region of the original image is cut out as the region of interest image may be stored separately. An example of saving an image related to the cut-out area is shown in FIG.
As illustrated in FIG. 7, for example, the generation function 102 acquires the cutout position image 701 on which the cutout window 402 illustrated in FIG. 4 is superimposed as a thumbnail, and displays the cutout position image 701 at the top of the thumbnail related to the region of interest image. May be. Thereby, the relationship between the original image and the region-of-interest image can be easily grasped.

  By displaying the image matrix information 505 in this way, the image matrix size of each series of medical images can be presented so that the user can easily understand.

In the case where the cutout process is performed a plurality of times, for example, 1024 × 1024 pixels may be cut out from 2048 × 2048 pixels, and 512 × 512 pixels may be further cut out from the cut out 1024 × 1024 pixels. In such a case, reconstruction matrix information of the original image is attached to the region-of-interest image with the image that is the previous cut-out source as the original image. That is, the reconstruction matrix information of the large medical image is inherited as the reconstruction matrix information.
According to the first embodiment described above, the region-of-interest image is attached to the region-of-interest image cut out from the original image by adding at least reconstruction matrix information as incidental information attached to the original image. It can be understood at a glance that the image is cut out from a certain image. That is, when saving to PACS or the like, the image matrix information of the original image cannot be saved, and it is possible to understand what kind of image the original image is even when clipping processing is necessary. That is, it is possible to easily identify that the image is cut out from the high-resolution image, and it is possible to easily perform the necessary correspondence according to the use such as interpretation or storage.

(Second Embodiment)
A conceptual diagram of the second embodiment will be described with reference to FIG.
As shown in FIG. 7, it is assumed that the medical image processing apparatus 1 is communicably connected to a plurality of servers that store images, for example, a plurality of PACS servers 801 and 802 via a network 850.

  When it is not assumed that there are a plurality of image matrix information of tomographic images, it is assumed that the image matrix information that can be stored in the PACS server is different. For example, the PACS server 801 may store a high-resolution medical image of 1024 × 1024 pixels, whereas the PACS server 802 may not be able to store an image of 1024 × 1024 pixels with a resolution higher than 512 × 512 pixels. .

  The second embodiment differs in that image matrix information that can be stored by the PACS server is stored in advance, and notification and cutout processing are performed when a medical image of image matrix information that cannot be stored by the PACS server is to be stored. .

A medical image processing apparatus according to the second embodiment will be described with reference to the block diagram of FIG.
The medical image processing apparatus 1 according to the second embodiment includes a correspondence table 901, a notification function 902, and an output function 903 in addition to the configuration of the medical image processing apparatus 1 according to the first embodiment.

The correspondence table 901 is a table indicating which image matrix information can be stored by the PACS server as the transfer destination.
The notification function 902 refers to the correspondence table 901 when there is an instruction to save the medical image from the user to the PACS server, and determines whether or not the medical image can be saved. Send a message prompting
The output function 903 outputs the region-of-interest image and the incidental information obtained by the clipping process to the PACS server.

Next, an example of the correspondence table 901 will be described with reference to FIG.
The correspondence table 1000 shown in FIG. 10 stores server IDs and storable image matrix sizes in association with each other. For example, referring to the correspondence table 1000, a PACS server with a server ID “1” can store all image matrix sizes, whereas a PACS server with a server ID “3” has 512 × 512 pixels, 1024 × 1024. It can be seen that although pixels can be stored, 2048 × 2048 pixels cannot be stored.

  Next, the operation of the medical image processing apparatus 1 according to the second embodiment will be described with reference to the flowchart of FIG.

In step S1101, a transfer instruction of a medical image to the PACS server is started by using a storage instruction (transfer instruction) to the PACS server from the user and the completion of the imaging process as a trigger.
In step S1102, the notification function 902 determines whether the transfer destination PACS server can store images other than 512 × 512 image matrix information. The determination may be determined with reference to a table. If it can be stored, the process proceeds to step S1103, and if it cannot be stored, the process proceeds to step S1104.

In step S1103, the medical image (original image) and the accompanying information are transferred to the PACS server.
In step S1104, the notification function 902 executes a cutting process for the user and notifies a message for generating a region-of-interest image. Note that the generation function may be set in advance so as to generate a region-of-interest image by cutting out a certain region.

  In step S1105, the output unit transfers incidental information including the region-of-interest image and the reconstruction matrix information of the original image to the PACS server. The operation of the medical image processing apparatus 1 according to the second embodiment is thus completed.

  If the size of the image matrix that can be stored in real time in the PACS server can be changed, the following processing may be performed. For example, the transfer restriction information indicating the size of the image matrix that can be stored by the PACS server is transmitted to the medical image processing apparatus 1 at a predetermined interval or at a timing when a storage instruction is received from the user. The notification function 902 may determine whether to perform cutout processing based on the transfer restriction information.

  Note that the completion of transfer of the region of interest image to the PACS server may be used as a trigger to delete the original image and the accompanying information, or may be deleted after being stored in the storage circuit 101 for a predetermined period.

  According to the second embodiment described above, a cutout process is performed with reference to the correspondence table indicating the storable state of the transfer destination server, so that a medical image (region of interest) having a storable image matrix size is obtained. Image) and a medical image can be appropriately stored in the server. In other words, it is possible to easily perform a necessary response according to the use such as interpretation and storage.

The X-ray tube 1213 includes a vacuum tube that holds a cathode that generates thermoelectrons and an anode that generates X-rays by receiving thermoelectrons flying from the cathode. The X-ray tube 1213 is connected to a high voltage generator 1217 via a high voltage cable. The high voltage generator 1217 is attached to the rotating frame 1211, for example. The high voltage generator 1217 generates a high voltage to be applied to the X-ray tube 1213 under the control of the gantry control circuit 1229 and supplies a filament heating current. The high voltage is applied between the anode and the cathode accommodated in the X-ray tube 1213. The filament heating current is supplied to the cathode of the X-ray tube 1213. The high voltage applied between the anode and cathode of the X-ray tube 1213 is called tube voltage. The flow of thermoelectrons generated from the cathode heated by the filament heating current under the high voltage and flying to the anode is called tube current. The high voltage generator 1217 adjusts the tube voltage and tube current to the X-ray tube 1213 according to the X-ray conditions.

The bed 1223 supports the top plate so as to be movable. A bed driving device 1225 is accommodated in the bed 1223. The bed driving device 1225 receives a drive signal from the gantry control circuit 1229 and generates power for moving the top and bottom, back and forth, and left and right. The bed 1223 positions the top so that the imaging region of the subject P is included in the FOV.

  The X-ray detector 1215 detects X-rays generated from the X-ray tube 1213. Specifically, the X-ray detector 1215 has a plurality of detection elements arranged on a two-dimensional curved surface. Each detection element has a scintillator and a photoelectric conversion element. The scintillator is formed of a substance that converts X-rays into light. The scintillator converts incident X-rays into a number of photons according to the intensity of the incident X-rays. The photoelectric conversion element is a circuit element that amplifies light received from the scintillator and converts it into an electric signal. For example, a photomultiplier tube or a photodiode is used as the photoelectric conversion element. As described above, the detection element may be an indirect detection type in which X-rays are converted into light and then detected, or a direct conversion type in which X-rays are directly converted into electrical signals.

  A data acquisition circuit 1219 is connected to the X-ray detector 1215. In accordance with an instruction from the gantry control circuit 1229, the data collection circuit 1219 reads an electrical signal corresponding to the intensity of the X-ray detected by the X-ray detector 1215 from the X-ray detector 1215, and reads the read electrical signal in the view period. To collect raw data having digital values according to the X-ray dose over the range. The data collection circuit 1219 bundles and collects the read electrical signals according to the resolution of the reconstructed image. The data collection circuit 1219 is realized by, for example, an ASIC (Application Specific Integrated Circuit) equipped with a circuit element that can generate raw data.

  The arithmetic circuit 1201 includes, as hardware resources, a processor such as a CPU, MPU, or GPU (Graphics Processing Unit) and a memory such as a ROM or a RAM. The arithmetic circuit 1201 implements a preprocessing function 1202, a reconstruction function 1203, an image processing function 1204, a system control function 1205, an auxiliary function 1206, and a generation function 1207 by executing various programs.

  In the preprocessing function 1202, the arithmetic circuit 1201 performs preprocessing such as logarithmic conversion on the raw data transmitted from the gantry 1200. The raw data after the preprocessing is also called projection data.

  In the reconstruction function 1203, the arithmetic circuit 1201 generates a CT image representing the spatial distribution of CT values related to the subject P based on the raw data after the preprocessing. As the image reconstruction algorithm, an existing image reconstruction algorithm such as an FBP (filtered back projection) method or a successive approximation reconstruction method may be used.

  In the image processing function 1204, the arithmetic circuit 1201 performs various image processes on the CT image reconstructed by the reconstruction function 1203. For example, the arithmetic circuit 1201 performs three-dimensional image processing such as volume rendering, surface volume rendering, image value projection processing, MPR (Multi-Planer Reconstruction) processing, and CPR (Curved MPR) processing on the CT image, and displays the displayed image. Is generated.

  In the system control function 1205, the arithmetic circuit 1201 comprehensively controls the medical image processing apparatus according to the present embodiment.
