| Research Abstract |
Proton therapy offers a unique opportunity for precise, localized irradiation for treatment of cancer and other diseases. Performance specifications of technical components of a hospital-based proton radiotherapy facility are presented. The technical items specified include : the accelerator ; the beam transport system including rotating gantry ; the treatment beam line systems including beam scattering and dosimetric instrumentation ; and an integrated treatment and accelerator control system. Patient exposure outside the designated treatment fields should be kept withim regulatory limits. Principles of ALAR A have been applied. The facility specified will meet the requirement of cost-benefit balance assessment. Operating costs for the facility must be kept at the lowest possible level. The operating costs include the utility costs, maintenace costs and operating personnel costs.
