Development of Proton Radiotherapy Facility

质子疗法为癌症和其他疾病的治疗提供了一个独特的机会，可以进行精确的局部照射。介绍了某医院质子放射治疗设备技术部件的性能指标。具体规定的技术项目包括：加速器；包括旋转龙门在内的束流传输系统；包括束流散射和剂量测量仪器在内的治疗束线系统；以及综合治疗和加速器控制系统。患者暴露在指定治疗区域之外的时间应保持在IM法规限制范围之内。应用了Alar A原理。指定的设施将满足成本效益平衡评估的要求。该设施的运营成本必须保持在尽可能低的水平。运营成本包括公用事业成本、维护成本和运营人员成本。

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.
