Treatment room switching and beam energy-changing automation system for proton therapy devices

Abstract

The invention relates to a treatment room switching and beam energy-changing automation system for proton therapy devices. The system includes: an accelerator control module; a mirror accelerator generation module connected to an accelerator device; and a treatment room switching module connected to the accelerator control module; and a condition monitoring module coupled to the accelerator control module, the image accelerator generation module, and the treatment room switching module. The system establishes a complete copy of the real accelerator device through a mirror accelerator technology to provide access to the treatment room, meets the need for the treatment room to detect the state of the accelerator, while avoiding the risk that the treatment room can incorrectly access the realaccelerator device. at the same time, on the basis of arbitrating and ordering the access requests of different treatment rooms by the treatment room switching module, the accelerator is operated infull dynamic circulation according to the treatment needs to generate beam output of different energies, and the final treatment needs can be satisfied.

Description

technical field [0001] The invention relates to the field of proton therapy, in particular to a treatment room switching and beam energy conversion automation system for a proton therapy device. Background technique [0002] Proton therapy accelerators generally include a variety of hardware devices, such as various magnets, power supplies, and microwave power sources distributed on rings and transport lines. During the treatment process, the control system of the medical accelerator needs to dynamically adjust and automatically run various accelerator equipment according to the energy demand of the treatment room, so as to realize the adjustment of the beam position and energy, so as to finally complete the radiation energy and precise treatment of the tumor site of the patient. Position control. For the proton therapy accelerator, in order to achieve the purpose of rapid and accurate treatment, the virtual slices of the tumor site are first layered during the treatment pr...

Problems solved by technology

However, if the treatment room needs to monopolize the accelerator beam, that is, to exclusively operate the accelerator equipment, it is generally necessary to use hardware to implement multi-way switch selection combined with software implementation, so the implementation of this method is complicated and requires the cooperation of software and hardware.

In addition, in the prior art, the treatment room is directly accessible to the accelerator equipment. If the parameter setting or process control is wrong, it may cause equipment damage or proton beam deflection and cause secondary radiation.
