Abstract

The invention relates to a fast-response scanning control system and method for an active variable energy point scanning power supply, characterized in that the fast-response scanning control system includes an AD board, a fast chain interface board, a state board, an FPGA controller and a PWM backboard; The AD board is used to obtain the feedback current of each branch in the active energy point scanning power supply; the fast chain interface board is used to receive the fast chain signal sent by the treatment terminal; the status board is used to judge whether there is a fault inside the active energy point scanning power supply , if a fault occurs, the fault signal is fed back to the FPGA controller in real time; the FPGA controller is used to monitor and determine the output current control signal of the active energy point scanning power supply in real time; the PWM backplane is used to determine the output current control of the FPGA controller in real time The signal generates multiple PWM optical signals in real time and sends them to the active energy-changing point scanning power supply. The present invention can be widely used in the field of ion accelerators.

Description

technical field [0001] The invention relates to a fast-response scanning control system and method for an active variable energy point scanning power supply, belonging to the field of ion accelerators. Background technique [0002] The ion accelerator treatment device is a large-scale radiotherapy device that uses ion beams for radiotherapy. Charged ions are accelerated by a synchrotron to a certain energy and then injected into the human body. After that, a large amount of energy will be released instantly, forming a pulse peak of "Prague" energy. The entire irradiation process is similar to the "stereotactic blasting" of tumors, which can powerfully kill tumor lesions while avoiding irradiation of normal tissues to maximize the curative effect. The beam distribution system is the hardware facility for ion beam radiation therapy, and it is also an important part of the ion accelerator treatment device, including beam distribution, monitoring, debugging, collimation, and me...
