Problems solved by technology

[0002] Radiation therapy, as one of the main methods for treating tumor diseases, has been widely used clinically. The precise control of radiation therapy dose is very important in radiation therapy and is the core content of precision medicine. High-energy X (γ) rays and electron rays There is a dose build-up effect. The dose after the dose build-up area is the actual dose acting on the human body. One of the depth dose distribution characteristics of different energy rays is that the surface dose decreases with the increase of the ray energy. The depth of the maximum dose point and the percentage depth dose The depth from the surface to the maximum dose point is the dose build-up area, which causes the problem of insufficient target dose in the treatment of superficial lesions (such as breast cancer, skin cancer, etc.). Therefore, in radiation therapy, tissue compensation is usually used To increase the superficial dose of the target area, the current practice is to scan the lesion with a CT scanner to obtain the patient's CT image data, transmit the patient's CT image data to the treatment planning system, and then obtain the radiotherapy plan through special 3D software The three-dimensional contour data of the tissue compensation film, and then the mold of the tissue compensation film is made by 3D printing to obtain a personalized tissue compensation film. Radiation will be generated under X-rays, which will cause certain damage to the human body. Therefore, it is necessary to design a 3D printing device for tissue compensation membranes for radiotherapy that is practical and reduces the radiation received by the human body.
