Design and Analysis of LINAC Control System in FPGA

Control system is the key part of Medical linear accelerator (LINAC), as the system deals with controlled radiation exposure to human body. As this sort of system pass through different regulatory body approvals, control system should be able to handle different stringent parameters very precisely. Some of the important tasks for control system are measurement of delivered dose; energy stabilization through controlling voltage level, automatic frequency control (AFC) of magnetron, trigger generation, human safety and machine safety interlocks etc. Proposed approach to the above mentioned requirement is design of a control system based on FPGA.This project proposes a control and communication system for medical linear accelerator.
