Problems solved by technology

[0004] According to the above, when using ultrasound-assisted CBCT for positioning verification, the scanning position, pressing depth, rotation angle and pressing force of the ultrasonic probe cannot be recorded, which is arbitrarily large, which is not conducive to improving the accuracy of ultrasound-assisted CBCT for positioning verification. Therefore, it is necessary to design a scanning device for ultrasound-guided radiotherapy to assist patient positioning to solve the above problems

Abstract

The invention discloses a scanning device for assisting patient in positioning during ultrasonic guided radiotherapy. The scanning device comprises a clamping plate, a base, a PLC control panel, a placement groove, a travel switch I, a travel switch II, an electric push rod I, a stepping motor I, a rotating shaft, an arc-shaped rack, a movable seat, a stepping motor II, a gear, an electric push rod II, a fixed seat, a pressure sensor and an ultrasonic probe. According to the invention, through the action of an X-axis, Y-axis and Z-axis electric position adjusting mechanism, accurate control over an ultrasonic guided scanning position is achieved; through the matching effect of an angle rotating and positioning device, the rotating angle of the ultrasonic probe is ensured; the design of a pressure sensing system is cooperatively used, so medical staff can conveniently master pressing depth and pressing force, and the precision of positioning verification of ultrasonic-assisted CBCT is improved; and in conclusion, by means of the device, the consistency of ultrasonic probe scanning in each time of positioning verification is guaranteed, and popularization and application of auxiliary positioning during ultrasonic guided radiotherapy are facilitated.

Description

technical field [0001] The invention relates to an ultrasonic scanning device, in particular to a scanning device for assisting patient positioning in ultrasound-guided radiotherapy. Background technique [0002] Tumor radiotherapy is one of the important means of treating malignant tumors. During the implementation of radiotherapy, the tumor and surrounding normal tissues and organs will be deformed to varying degrees, which will lead to a decrease in the dose to the tumor target area or an increase in the dose to normal tissues. As a conventional radiotherapy technique, image-guided radiotherapy fully considers the organ movement caused by respiratory movement and other functional movements during a single treatment and the patient's body position deviation between fractionated radiotherapy, and reduces the setup error and radiation dose deviation caused by organ movement. Further improve the accuracy of radiotherapy, so that the tumor target area is fully irradiated, and ...
