Abstract

The invention relates to a radiotherapy dose monitoring device with a self-recovery function. The device comprises at least one dose detector unit, at least one self-recovery current frequency conversion unit, an FPGA unit and a radiotherapy control unit. Each dose detector unit is arranged at a radiotherapy terminal and is used for detecting a beam signal of the radiotherapy terminal and outputting a continuous current pulse signal; each self-recovery current frequency conversion unit is used for converting a current pulse signal output by each dose detector unit into a digital pulse signal; the FPGA unit is used for calculating according to each path of digital pulse signal to obtain a corresponding total irradiation charge quantity Q; and the radiotherapy control unit is used for obtaining the corresponding irradiation dose according to the proportional relation between the total charge quantity Q and the actual irradiation dose. The device can be widely applied to the field of medical particle radiotherapy equipment.

Description

technical field [0001] The invention belongs to the field of medical particle radiotherapy equipment, in particular to a radiotherapy dose monitoring device with self-recovery function in particle radiotherapy. Background technique [0002] In particle radiotherapy devices, radiation dose monitoring is a key factor affecting the safety of treatment and the effect of radiotherapy. In a high-precision particle radiotherapy system, the beam output from the treatment terminal needs to accurately calibrate the radiation dose when performing radiotherapy on human cancer cells. Then determine the radiation duration of radiotherapy. [0003] However, conventional dose monitoring devices have problems such as low accuracy, poor stability, high failure rate, and poor reliability, which can lead to unsatisfactory radiotherapy effects, waste of radiotherapy beam resources, and increased patient safety risks and medical costs. SUMMARY OF THE INVENTION [0004] In view of the above pr...
