Interlocking system for particle dose safety protection

Abstract

The invention discloses an interlocking system for particle dose safety protection. The system includes particle accelerators, an in-accelerator beam cut device, treatment room front end beam cut devices, a beam dose detection device, multiple treatment rooms, transmission system main line beam cut devices, a first controller and a second controller, wherein the beam cut devices are disposed in the particle accelerators, and the transmission system main line beam cut devices are disposed on a main beam transmission line. The system is advantaged in that the system is tested through beam dose monitoring devices in the treatment rooms, once the dose delivered to a patient body is found to be out of the safe range, interlocking is triggered immediately, the beam cut devices at the different locations in a particle therapy system are controlled for beam cut, in this way, the purpose of multi-point beam cut and redundant beam cut is achieved, safety and redundancy of the interlocking systemare guaranteed, and safety guarantee is provided for particle radiotherapy.

Description

technical field [0001] The invention belongs to the field of particle medical safety interlocking, and relates to a particle dose safety protection interlocking technology, in particular to a particle dose safety protection interlocking system. Background technique [0002] In particle radiation therapy for cancer treatment, the accelerator accelerates the particles to a certain energy, and then sends the particle beam to the treatment room to irradiate the patient. In case of an emergency, in order to prevent the particle beam irradiated into the patient from exceeding the safe dose, the beam needs to be cut off immediately. Since the particle therapy system is very large and the distance from the accelerator to multiple treatment rooms is long, the efficiency of beam cutoff is slow. , and the safety of the particle therapy system for patient treatment, and the amount of radiation generated when the beam is cut off is large, which is easy to cause damage to the patient's bo...
