Abstract :
A new real-time control and calibration system has been installed at the Fermilab Neutron Therapy Facility. An IBM-PC/AT user console is networked to the VME-bus-based front-end computers using a token-ring local area network. Two 68000-based single-board computers are used in the front-end station to isolate the time-critical dose measurement and accumulation tasks from the network functions. The system is fabricated from commercially available computer, memory, and data acquisition cards. Software in the front-end processors is written in assembly language, but application programs for the IBM-PC/AT are written in Turbo Pascal. Chamber calibration, beam calibration, and patient dose delivery functions are all controlled through the IBM-PC/AT by the radiation therapists. Records of each treatment are printed automatically after the prescribed dose is delivered
