Problems solved by technology

However, the ultrasonic imaging field of view is small, and abdominal organs or tumors that are greatly affected by respiratory movement may cause the tracking marks of the organ or tumor to exceed the field of view of the ultrasonic image due to excessive movement, or the appearance of the tracking marks of the organ or tumor will change due to excessive deformation of the organ Larger, causing tracking failure and affecting motion evaluation

Abstract

The invention discloses a movement management method combining ultrasonic wave with an abdominal pressure plate. Amovement management device based on combination of ultrasonic wave and an abdominal pressure plate comprises the implementation steps that S1, an ultrasonic probe and an abdominal pressure plate are connected to a bed plate, and it is guaranteed that the ultrasonic probe and the abdominal pressure plate are fixed relative to the position of the bed plate when ultrasonic data are collected, namely, the ultrasonic probe and the abdominal pressure plate are fixed in a laboratory or treatment room coordinate system; S2, the compression position and the height of the abdominal pressure plate are adjusted, the patient is forced to enter a shallow breathing state, and the position of the abdominal pressure plate is recorded; S3, the scanning position and the height of the ultrasonic probe are adjusted, and the positions of the ultrasonic probe in the horizontal direction and the vertical direction are recorded; and S4, the ultrasonic probe collects an abdominal ultrasonic image of the patient at the adjusted position, the tracking algorithm tracks the movement of the organ or tumor of interest in the ultrasonic image, and the position, the movement amplitude and the deformation degree of the organ or tumor of interest are obtained. According to the invention, the motion amplitude and deformation degree of the abdominal organ or the tumor are reduced, and the traceability and tracking reliability of the abdominal organ in the ultrasonic image are improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a motion management method for radiotherapy combined with ultrasound and abdominal pressure plate. Background technique [0002] As a device that compresses the abdomen to force the human body to breathe shallowly, the abdominal compression plate has been widely used in radiotherapy. The existing exercise management method combined with the abdominal compression plate is CT or X-ray fluoroscopy, which is used to detect the movement of abdominal organs or tumors. It has been verified that the abdominal compression plate can effectively reduce the range of motion of abdominal organs or tumors. However, the soft tissue resolution of CT or X-ray fluoroscopy is not good, and the information provided is limited. At the same time, the patient receives an additional radiation dose, which increases the burden on the patient's body. Ultrasound imaging has the advantage...
