Description of the Invention: [Technical Field] The present invention relates to the field of treatment of arteriosclerosis, and more particularly to a system for reducing vascular plaque. [Prior Art] Cardiovascular disease is a major cause of disease and mortality worldwide. The cause of cardiovascular disease is due to the formation of plaques in the coronary arteries for a period of time, which leads to a decrease in blood flow into specific organs such as the brain and myocardium. In some cases, a decrease in blood flow may cause transient cerebral ischemia, calf cramps, or angina. If the occlusion of the artery is more pronounced, it may damage the brain, leg or heart muscle and even be fatal. The treatment (nursing) of vascular disease and the avoidance of further damage to the tissue is to eliminate plaque by invasiveness. It is usually done by invasive surgery. Another alternative is balloon vascular prosthesis, which involves catheterization into the blood vessel. In this surgical procedure, the cap can be used for percutaneous engraving. Characteristics of the New Blocks When vascular repair is used, new blood vessels can be transplanted around the plaque area during vascular or cardiac surgery. In some patients, vascular prosthetics and bypass surgery cannot be performed 'such as when the patient is older or weaker, or when the block cannot withstand any treatment. In such a case, the patient must try Controlling _ disease by medicine, for example, by making (four) things. Because the surgical treatment of arterial Wei is invasive, the slanting of the ship will be smooth, and all of the (four) people will be combined. Therefore, a less invasive method is needed to reduce the arterial _ block formation. For the treatment of weaving and blood vessels (4), the method of recording invasiveness is usually a heart = tube 'has been touched', for example, the patent of US Patent No. 5,657,76 to !, 524, 62 °. _ ‘ these methods and “combined:: reduce plaque, not to mention in the vascular system. BRIEF SUMMARY OF THE INVENTION The present invention is directed to a method and system for reducing vascular plaque. To achieve this, the term "heart rhythm" refers to all or any event related to blood flow that occurs during the start of a heartbeat and the beginning of the next heartbeat. Each single "beating" of the heart involves three main phases: atrial contraction, ventricular contraction, and complete diastole. According to the present invention, there is provided a method of non-invasively reducing arterial plaque comprising the steps of: imaging at least a portion of a mammalian body to produce an image; beta determining a location of at least one plaque in the image; Determining the base of the plaque, the location of the base being the target location; accurately determining the relevant location of the target location associated with the heart rhythm in the animal; transmitting a supersonic energy beam from a source to the relevant location The focus is to increase the temperature of the target location in a predetermined manner; to monitor the temperature of the target location; and to 'send the transmission of the ultrasonic energy wave when the target location reaches the predetermined set temperature. A method associated with the present invention includes the steps of displaying the image and the location of the target. ^ The method also includes a preparation step for a treatment plan for treating the vascular plaque. The frequency of the ultrasonic energy wave is adjusted between 0.8 Hertz and approximately 4 Hertz. For example, the focus of the ultrasonic energy beam is less than about 15 mm3. The intensity of the ultrasonic energy wave is typically adjusted to be greater than about 500 WW. In addition, the transmission duration of the ultrasonic energy wave is usually adjusted in accordance with changes in temperature. Typically, the transmission duration of the ultrasonic energy beam is adjusted to between about 8 〇ms and 乜. According to another feature of the invention, a system for reducing vascular plaque is provided, comprising: 'an imaging device for imaging at least a portion of a mammalian body; an interpreting device for interpreting the image to locate At least one gray tube plaque and a base of the blood vessel plaque to determine the location of the plaque; Λ 5 201016196 a monitoring device for monitoring the relative position of the target site of the heart rhythm; for supersonics of predetermined intensity An at least one replaceable ultrasonic transmitting device that transmits an energy wave to the target location; a temperature monitoring device for monitoring the temperature of the target location; and means for turning off the transmission of the ultrasonic energy wave when the target location reaches a predetermined set temperature.

The hfu device is adapted to transmit the hpu to the base of the plaque as the target location by the imaging and interpretation device. The temperature monitoring device can detect the temperature of the tissue at the target location via thermal imaging to determine the completion of the transmission. ' According to this hair _ secret Kelin treatment of the artery, intestine f, thigh or coronary artery plaque. According to other embodiments of the present invention, the ECG device is adapted to monitor the heart rhythm during the treatment and to process signals from the monitored ECG. The control device controls the time of imaging and the transmission of the lungs based on the data received from the ECG monitoring towel so that the ray transmission and reading are triggered at specific points within the cardiac cycle. The control device is adapted to direct the ultrasonic transmitting device to emit the ultrasonic energy wave and determine: a specific angle or location of the transmission; the intensity of the transmitted ultrasonic energy wave; and the duration for transmitting the ultrasonic energy wave. The above parameters are determined by the domain to hide the donation and the location. The treatment plan is based on a treatment plan that sends a number of supersonics. The system = device 'secret' from the automatic unit and / / money to intervene to receive the sending surface to the base of the plaque will cause the tissue temperature of the target location to rise. Head 6 201016196 MRI monitoring of the target tissue detected an increase in temperature. When the temperature rises enough, stop * treatment. The HFU treatment can be repeated at the same target but with another delivery angle. HPU treatment can also be repeated within the same plaque or at multiple target sites within different plaques. The HFU is continuously sent for each target until a sufficient amount of treatment has been sent resulting in scarring and plaque degradation. [Embodiment] Fig. 1 shows a system for non-invasively reducing vascular plaque. The patient 10 is treated with an ultrasonic transmitting device, typically by means of a high frequency ultrasonic (High FreqUency® tHtrasomKi; qing) transmitting device. During the course of treatment, the patient is simultaneously monitored by electrocardiogram (ECG) monitoring device 30 and magnetic resonance imaging (Magnetic Resonance Imaging; device 4〇. ecg monitoring device 30 and MRI device 4〇 are transferred to the treatment. The device 5 includes an image recognition device 60 and an image display device 70. The controller provides an output to the steering unit 8〇, which diverts and controls the MN transmission device to guide the transmission of energy. The patient 10 is located in a comfortable position on the treatment table. At this position, the patient*, v page remains stationary and the self-treatment process is non-invasive, so it can be performed without any sedation treatment and does not induce the patient's discomfort. The station is located inside the device 使得 ^ so that the MRI image can be obtained during the treatment, the target is touched, and the progress of the treatment is monitored. On the back of the plaque on the gray wall, the device must provide a fast and detailed image of the artery. So that the base of the plaque can be accurately identified. ^^ Device 4〇 provides images that can be seen in the case of nanometer resolution, such as 1.5, 3 Or a 7 Tesla® device that can be used in embodiments of the present invention to provide these accurate images. The patient 10 can also be monitored during the treatment using the ECG monitoring device 30. The ECG monitoring device 30 can be a standard 12-lead ECG or can be utilized With less guidance to implement all other components used in or near the device 4, the ECG_, device 30 must not include any iron-containing material. The patient's heart beat causes all the arteries of the heart to move as The arteries are expanding each time the heart contracts. The ecg system compensates for this movement. In order to obtain useful images, the dirty beats of the patient 7 201016196 are taken to obtain images so that each image is at the same point in each heartbeat cycle. Obtained. For example, 'when the heart is relaxed, the device can arrange to obtain images when the heart is dilated. Similar 'use ECG monitoring device 30 to make the transmission of HFU treatment correspond to the heartbeat cycle. HFU treatment is used after the target location is confirmed using MRI images. At the target location. In order to determine the correct target location during treatment, MRI is obtained during the cardiac cycle. The time point of the image is the same as the time point at which the HPU treatment is sent. According to this method, the target location confirmed by MRI is the same as the location where the HFU treatment is delivered. The ECG data is transmitted to the treatment device during the treatment. The device 5 interprets the ECG data and provides instructions to the MRI device 40 and the HFU controller 80. The processing device 50 also receives data from the MRI device 40 and includes an image recognition device 6 and an image display device 70. The image recognition device 60 The plaque in the artery can be discerned by interpreting the signal in the image. Alternatively, the clinician can visually discern the plaque on the image display device 70 of the Mjy image. In some embodiments, image recognition device 60 identifies the plaque ' and the clinician utilizes image display device 7 to verify the identification. The image recognition device 60 and/or the clinician identifies the location of the base of each plaque, which is the target of HFU therapy. After the treatment device 50 and/or the clinician identifies one or more target locations, a treatment plan is presented. A single plaque can include a target location or a number of target locations along the base of the plaque. In addition to this, one body can have multiple plaques. In some cases, the treatment plan will include sending HFUs to all of the identified plaque bases. In other cases, it is desirable to selectively treat only some of the plaque base or part of the plaque base while leaving other untreated plaque bases. Therefore, the treatment plan includes determining which plaques are to be treated and turning those locations into destinations. The ideal alignment of the HFU device 20 to the patient 10 must also be determined for each target location. This will depend on where the target is located and factors such as individual patient analysis. The following parameters depend on the size and location of the plaque depicted by MRI device 40: the particular angle or location of the transmission; 8. 201016196 The intensity of the transmitted ultrasonic energy wave; and the duration used to transmit the ultrasonic energy wave. In some cases, treatment can be performed by a single angle of stationary HFU beam. Alternatively, the HFU can be better transmitted to the target location using more than one treatment angle of the stationary HPU beam. In some cases, jjpu can be sent as the beam is rotated by the arc of the treatment angle. In other cases, the HFU can be sent by multiple arcs of the treatment angle. This can be achieved with a multifocal converter. The method includes the step of replacing the source of the beam. This replacement can be linear or angular. By using more than one treatment angle to deliver treatment, the energy delivered to the tissue outside the target site is minimized, and thus the risk of damage to other tissues can be reduced or eliminated. The target temperature must be selected for each treatment angle and location of each treatment. So the treatment plan includes which

However, due to the movement of the artery, the rotation of the arterial U treatment can be sent only at the specific time of each pie. (d) p towel is provided. Because: The arc of the treatment can be formed by a series of small arcs, which are treated by a series of small arc rotations to send the HPU every time the heart beats. For example, at the first heartbeat, treatment can be initiated and rotated at the first angle. With the next heartbeat, the second angle can be re-treated and rotated "the second small arc of the Hi multiple J 丨 coherent. Therefore the treatment will be continuously rotated through a small arc until these small arcs into treatments The arc of the painting is stopped. Another way 疋 ' During HFU treatment, the static treatment can be sent on the arc of the angle without using .201016196 f. For example, 'in the first heartbeat' can send the stationary lung beam at the _ angle The brain device can be slightly adjusted, for example, lmm, and in the second heart, 'the second angle is treated by the stationary HFU device, and the second angle can be close to the first angle. The HFU device can be continuously Adjust the continuous treatment angle until the treatment is sent at a series of angles to form an arc of the treatment angle. Another way is to adjust the size and pattern to the multi-focus transducer of the target tube, or have more than one way of succession The arc of the transducer that transmits the energy. The processing device transmits the HFU controller 80 to the recording device 2〇 according to the treatment plan weaving order. When the HPU transmitting device 2 is located in the device 4, it must not Including any iron-containing material. During the treatment, the treatment surface of the jjPU transmitter device is in direct contact with the patient's 1G body surface, or with the patient's neck or mouse town or by an intermediate medium such as a gel patch. Chest contact. When a gel piece is used, pressure can be applied to correct the distance between the patient's body surface and the target location within the blood vessel. Therefore, the squeezing patch is suitable for use in a therapeutic device that needs to rotate and transmit HFU on a therapeutic arc. In the drawing, when the device rotates around the target location, the distance between the device and the target location maintains the chirp-frequency super-chopper transmitting device 20 in a movable manner, and the patient can be accurately positioned and adjusted to directly shift the HFU. The target location is accurately generated. The maximum distance between the high frequency ultrasonic transmitting device 20 and the target location is preferably less than about 6 cm. This maximum distance can be considered when generating the treatment plan. The ultrasonic transmitting HFU transmitting device 20 transmits the ultrasonic wave to The target of the base of the plaque is to raise the temperature of the target location. The size of the HFU focus is preferably less than about 15mm3 'The size of this HFU focus can be This is achieved with HFU waves having a frequency of approximately 至8 to 4 Hertz and a focusing intensity of approximately 500 to 3000 W/cm2. The HFU transmitting device 2 transmits the HFU to the specific location within the target location in accordance with the instruction of the processing device 50 in a repeated short interval At the point, the intervals are associated with a specific point within the cardiac cycle detected by the ECG. Each HFU transmission duration may be from about 80 ms to about is. The appropriate duration of each Hpu transmission depends on each patient's Heart rate. The duration of each HFu transmission may be a short duration suitable for most or all patients, regardless of the patient's heart rate. Alternatively, the duration of each HFU transmission may depend on •201016196 The measured heart rate is determined for individual patients. Finally, the duration of each HpU transmission can be varied during the treatment of each patient in response to the measured heart rate. The HFU transmitting device 20 continuously transmits the HFU to the target location until the tissue reaches the temperature required for the treatment plan. In some embodiments, the maximum desired temperature of the target location is approximately 80 degrees Celsius. The temperature at the target location is based on the mosquito screen provided by the device 4G by the processing device %. In order to increase the temperature, the system can periodically acquire images during the treatment. For example, the system can be acquired after each transmission - it is difficult. In addition, an MRI can be obtained during the Send ® process. For example, an MRI image can be rotated at the initial treatment order and then reproduced after several HFU pulses. Then multiple images can be reproduced during the monitoring process. The MR! image signal at the target location is changed in a manner that corresponds to the tissue temperature. The processing device 50 includes means for interpreting changes in the image of the target location to determine the temperature of the tissue. The processing device 50 Hz HFU controller 80 intermittently transmits hfu when the desired temperature is reached. Figure 2 shows a method of treatment in an embodiment of the invention. Treatment begins in step 1〇〇. In step 102, an image of the coronary blood vessel is taken. This image is used to identify the plaque at the base of the plaque in step 1〇4 and the target location. According to the image, in step 1〇6, the reference treatment device and/or the clinician can make a treatment plan. In step (10), the treatment is applied to the gold tube by the stationary ultrasonic beam or the rotating ultrasonic beam. The precise location within the wall. MRI imaging of the target location is performed in step 11 wipes. The imaging step determines if the desired temperature is reached based on the treatment plan made in step 112. If not, repeat the treatment step 108, the MRI imaging step 11 〇 #面影像处理步骤 112 ' until the desired temperature is reached. In step 114, it is determined whether the treatment plan needs to further determine the treatment angle or the treatment angle arc. If it is desired to plan the treatment angle or the treatment angle arc, then in step 116, 'adjust the starting position and starting angle of the MN launcher, and in step 1 〇8, the treatment will be treated at a new angle. Applied to the same target location. The bribe and image processing are repeated in steps 110 and 112 until the desired temperature is reached using the new 201016196 hfu device angle. When there is no further treatment plan for the target location, then a decision is made in step 118 regarding the further treatment plan for the other target location. If there is no treatment plan for other target locations, then the treatment will end in step 122. However, if there is a plan for further treatment location, then the location of the device is adjusted in step 12 to send the HFU to the new target location and the process is repeated for the new target location. This process is repeated 'until all the project target locations have been processed. ▲ The temperature of the target tissue in the vessel wall is raised by f by applying HFU to the base of the plaque. This increase in temperature can lead to inflammation of the tissue, which is sufficient to reduce or damage the vascular avascular tube (vasava_m), which is supplied to the plaque by the autologous vascular line. It is believed that vascularized damage to the vessel wall at the base of the plaque results in the final degradation of the plaque. 13 is not a miscellaneous HFU, it can be used to the base of the plaque without damaging the blood vessel wall. In this manner, HPU treatment can be used to non-invasively reduce or eliminate plaque. The use of target ultrasound therapy in embodiments of the present invention treats atherosclerotic disease non-invasively, thereby avoiding the risk of being present in invasive treatment. In addition, by avoiding surgery, the treatment process is simpler for the patient and the clinician, and can be performed more quickly and the patient's pain is alleviated faster and easier to recover. In addition, a treatment option is provided for patients who cannot undergo surgical intervention. While some embodiments of the invention are applicable to the aorta, this treatment can also be used to reduce arterial stiffness at other locations in the body, including coronary arteries. Image-guided cardiac ablation methods and systems have the potential to be used in vascular applications as described below: 'To eliminate arteriosclerosis, including removal of atherosclerotic plaque, usually in the thigh, carotid artery, kidney or coronary artery . It can also be used to eliminate thrombolysis, including intracranial thrombosis, thrombosis in the hemodialysis shunt, thrombosis in the left atrial appendage (LAA), venous thrombosis, and pulmonary embolism. It can further be used to eliminate typical vascular occlusion in physical conditions, such as bleeding, puncture sealing, varicose veins, pseudoaneurysm, vascular malformation in the brain, anemia of the organ, and bleeding esophageal varices, with 12 201016196 and To divide the twins sharing a single placenta. The image-guided method and system have the potential to extend the following non-vascular applications: New Zealand cancer has _the situation including prostate cancer, breast cancer, hepatocellular carcinoma, kidney, pancreatic tortoise and kidney cancer. It can also be simpler than other non-vascular applications, heart |± cancers such as benign prostatic hypertrophy, uterine fibroids and fibroids (chest, liver). In addition, the image-guided cardiac exfoliation method and system can be used to treat glaucoma, pain treatment, 'large _ Weier dysfunction (_ disease, Parkin Hehe syndrome), lithotripsy
