Real-Time Computer Verification for Radiation Therapy Treatment Machines

Abstract

A computer based verification system which monitors the operation of a 4-MV linear accelerator is described. Fourteen parameters can be checked for proper alignment prior to irradiation. A training simulator was also built to minimize interference with treatment schedules and to provide technicians with experience in using the system during the developmental stages of the project.

QA Issues for Computer-Controlled Treatment Delivery: This Is Not Your Old R/V System Any More!

“…Many standard QA measures were developed to avoid these common transcription errors, including many recommended by AAPM TG40(2). R/V systems were developed to reduce the frequency of these common random treatment errors (3)(4)(5)(6). Treatment error rates with R/V were reported to range from 0.5% to 3% per session (3,5,7).…”
