Electronic beam whole-body radiotherapy positioning platform

The invention discloses an electronic beam whole-body radiotherapy positioning platform, and is used for the field of medical apparatus. The positioning platform comprises a lifting platform and a rotating disc arranged at an upper side of the lifting platform, the rotating disc is connected with the lifting platform through a central rotating shaft, a diffuser screen supported upwards is arranged on the lifting platform at one side of the rotating disc, and a dosage detection device is arranged on the diffuser screen. In the electronic beam whole-body radiotherapy positioning platform, the rotating disc is arranged on the lifting platform, in use, the space between the rotating disc and an accelerator is set, then a patient stands on the rotating disc, the radiotherapy irradiation body position is precisely controlled by shifting the rotating disc, at the same time, in cooperation with the dosage detection device on the diffuser screen, the irradiation dosage of different positions is monitored in real time, and parameters are accurately determined, including the distance between a body surface of the patient and a ray source of the accelerator, the dosage distribution characteristics after an irradiation field is amplified, body surface dosage distribution rules, the output dosage rate of long-distance irradiation of the accelerator and the like. The electronic beam whole-body radiotherapy positioning platform is simple in structure, and facilitates electronic beam whole-body radiotherapy.
