Abstract

In order to solve the technical problems that the position of the Cherenkov radiation signal collected by the existing real-time monitoring synchronous acquisition device for tumor radiotherapy may be inconsistent with the position of the radiation target area, and the specific deviation position and causes cannot be located when clinical deviations occur. The invention provides a real-time monitoring and positioning device for the position and dose of radiotherapy based on CLI and structured light technology, and a tumor radiotherapy system. The invention obtains the three-dimensional body surface dose distribution of the patient in real time through three CLI cameras, obtains the three-dimensional body surface contour distribution of the patient in real time through three sets of position synchronous monitoring modules, and realizes the registration and fusion of the three-dimensional body surface dose and the body surface contour through spatial coordinate transformation. , to monitor the accuracy of patient radiation dose and treatment location in real time. Once the position dose exceeds the clinical deviation, the exact position of the dose deviation can be located, and the cause of the deviation can be determined to provide a basis for adjusting the patient's position or accelerator dose.

Description

technical field [0001] The invention relates to a real-time monitoring and positioning device for radiotherapy position and dose, and a tumor radiotherapy system based on Cherenkov light luminescence imaging technology and structured light technology. Background technique [0002] Cerenkov Radiation (CR) means that when a high-speed charged particle travels in a non-vacuum medium, when the speed of the particle is greater than the speed of light passing through the medium, local polarization will be generated in the direction of the motion path, and Visible and near-infrared photons are released in the process of returning to the equilibrium state. Similarly, the phenomenon of Cherenkov radiation (CR) occurs when radioactive particles enter biological tissues. [0003] Robertson et al. applied Cerenkov radiation to the field of biomedical imaging for the first time and proposed the concept of Cerenkov Luminescence Imaging (CLI). Cerenkov luminescence imaging (CLI) technolog...
