放疗计划系统(Radiation Therapy Treatment Planning Sy stem, TPS) 曲桂红 PhD 2006/10/21 放疗计划系统(Radiation Therapy Treatment Planning Sy stem, TPS) 1、 定义 IEC 60601-2-48, Medical electrical equ ipment, Part 2: Particu lar requ irement for the safety of radiation therapy treatment planning sy stem
A RADIATION THERAPY TREATMENT PLANNING SYSTEM is a medical dev ice that simu lates a proposed RADIOTHERAPY treatment throu gh a process of modeling both a sou rce of radiation and a PATINT
It also often produ ces estimations of ABSORBED DOSE distribu tion in the PATIENT u sing a specific algorithm or algorithms
放疗计划系统是一种通过对放射源及患者建模过程来模拟一个推荐的放射治疗的设备
系统采用一个或几个专门的算法计算患者体内吸收剂量分布
放射治疗计划系统是放射治疗QA 必不可少的工具
