Embodiment Construction

[0063] The present invention will be further described below in conjunction with accompanying drawing.

[0064] Such as figure 1 , 5 As shown, the radiotherapy position and dose real-time monitoring and positioning device provided by the present invention includes a position synchronous acquisition module, a dose synchronous acquisition module, a communication and trigger module packaged in a high-energy ray shielding shell, and a high-energy ray shielding shell. The image reconstruction module, position dose deviation acquisition module and radiotherapy effect judgment module on the external computer (the image reconstruction module, position dose deviation acquisition module and radiotherapy effect judgment module are program instructions running on the computer).

[0065] The high-energy ray-shielding shell is made of high-absorption lead alloy or black alloy to prevent the radiation emitted by the accelerator in the tumor radiotherapy system from affecting the dose synchr...

Abstract

The invention provides a radiotherapy position and dosage real-time monitoring and positioning device based on a CLI and structured light technology, and a tumor radiotherapy system in order to solvethe technical problems that the position of a Cherenkov radiation signal acquired by an existing tumor radiotherapy real-time monitoring synchronous acquisition device is possibly inconsistent with the position of a radiation target area, and the specific deviation position and causes cannot be positioned when a clinical deviation occurs. Three-dimensional body surface dose distribution of a patient is obtained in real time through three CLI cameras, three-dimensional body surface contour distribution of the patient is obtained in real time through three sets of position synchronous monitoringmodules, registration fusion of the three-dimensional body surface dose and the body surface contour is achieved through space coordinate transformation, and the accuracy of the radiotherapy dose andthe treatment position of the patient is monitored in real time. Once the position dose exceeds the clinical deviation, the accurate position of the dose deviation can be positioned, the deviation reason can be judged, and a basis is provided for adjusting the body position of the patient or the dose of an accelerator.

Description

technical field [0001] The invention relates to a radiotherapy position and dose real-time monitoring and positioning device and a tumor radiotherapy system based on Cerenkov photoluminescence imaging technology and structured light technology. Background technique [0002] Cerenkov radiation (Cerenkov Radiation, CR) refers to that when high-speed charged particles travel through 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 moving path, and Visible light and near-infrared photons are released during the process of returning to an equilibrium state. Similarly, Cherenkov radiation (CR) phenomenon also occurs when radiation particles enter biological tissues. [0003] Robertson et al. first applied Cerenkov radiation to the field of biomedical imaging and proposed the concept of Cerenkov Luminescence Imaging (CLI). Cerenkov luminescence imaging (CL...
