Radiotherapy operation system based on motion capture

Abstract

,The invention discloses a radiotherapy operation system based on motion capture, relates to a radiotherapy operation system, and solves the problems that: when an existing master-slave robot operation system is used, all parts of a body need to be cooperatively matched for common operation, the operation burden is heavy, a main hand mechanism of the operating system is limited by the structure ofthe main hand mechanism, and the arm movement stroke of an operator is influenced. The system comprises a motion capture system, an upper computer and a handheld tool which are located in an operating room, and a surgical mechanical arm and a visual collector which are located in the operating room; at least three infrared target balls are adhered to each of four parts, namely a big arm, a forearm, a hand back and a hand-held tool of an operator; and a motion capture lens collects images of the infrared target balls on the four portions of the operating arm of the operator and uploads the images to the upper computer to be processed, the spatial positions of all the infrared target balls on each portion are obtained, and a control instruction is generated according to the spatial positions of all the infrared target balls on each portion to control the surgical mechanical arm. The system is mainly applied to radiotherapy operations.

Description

technical field [0001] The invention relates to a radiation therapy operation system, in particular to a radiation therapy operation system combined with a motion capture device. Background technique [0002] Particle implantation brachytherapy is to implant radioactive particles into the tumor through a puncture needle, and kill cancer cells through the rays produced by decay. At present, this technology has been put into clinical treatment. Due to its ability to reasonably control the radiation dose and small surgical wounds, it has advantages in various cancer treatment options. The use of seed implantation brachytherapy surgery can achieve a high surgical success rate and a small recurrence rate. However, in the current application, this surgical plan has problems such as relying on the doctor's surgical experience and errors in the implantation position. Since the surgical process requires multiple use of CT, and the implanted particles themselves carry radiation, the ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the existing master-slave robot operating system is used, all parts of the body need to be coordinated and jointly operated, and the operation burden is heavy; and the master hand mechanism of the operating system is limited by its own structure, which affects the movement of the operator's arm. The invention provides a radiotherapy operation system based on motion capture
