System and method for assisting radiotherapy on basis of infrared and visible light three-dimensional reconstruction

Abstract

The invention discloses a system and a method for assisting radiotherapy on the basis of infrared and visible light three-dimensional reconstruction. The system comprises a visible light three-dimensional reconstruction system, a near-infrared three-dimensional reconstruction system, a synchronous trigger device, a first calibration plate and a second calibration plate. The visible light three-dimensional reconstruction system comprises a visible light camera and a visible light projector; the near-infrared three-dimensional reconstruction system comprises an infrared camera and an infrared projector; the synchronous trigger device is connected with the visible light camera, the visible light projector, the infrared camera and the infrared projector; the first calibration plate can be arranged in the center of an accelerator of a therapeutic bed and is used for calibrating the visible light camera and the infrared camera; the second calibration plate is used for calibrating the visiblelight projector and the infrared projector. The system and the method have the advantages that the system is an infrared and visible light combined three-dimensional reconstruction system, and distance measurement, position verification, dynamic tracking, real-time monitoring and the like in clinical medicine can be carried out on therapeutic beds by the aid of the system and the method.

Description

technical field [0001] The invention belongs to three-dimensional reconstruction, medical image and binocular vision system, in particular to a radiotherapy auxiliary system and method based on infrared and visible light three-dimensional reconstruction. Background technique [0002] With the rapid development of radiation physics technology, computer technology and medical imaging technology, advanced radiation therapy technologies such as three-dimensional conformal radiation therapy, intensity-modulated radiation therapy, volume rotation intensity-modulated radiation therapy and helical tomotherapy are constantly innovating. The new technologies represented by radiotherapy, dose-guided radiotherapy and radiomics have pushed radiotherapy towards the era of "three precision radiotherapy" with "precise positioning", "precise planning" and "precise treatment" as the ultimate goals. [0003] The automatic positioning system is an auxiliary radiotherapy system based on machine ...

AI Technical Summary

Problems solved by technology

[0008] (1) The marker points are easy to fall off and shift, which will have a great impact on reconstruction and tracking;

[0009] (2) The light of the marked point is easily blocked, which will limit the doctor's active operation area in actual clinical use;

[0010] (3) Before the operation, it is necessary to perform another CT or MR scan on the patient with the sticker, which increases the burden on the patient
