摘要:
CT模拟定位在放疗中提供原始坐标定位和复位等功能，为放疗提供影像与坐标信息。通过电子密度标定，校正组织不均匀性，为放疗计划系统剂量计算提供支持。本文结合相关国家标准、国际指南、CT模拟定位机临床功能与本中心实践经验，提出一套适用于放疗大孔径CT模拟定位机验收与服役测试方案。可指导和协助新开科室进行较为全面、安全且可行的验收服役测试流程，内容包括CT模拟定位机的机械、图像质量、辐射剂量、放疗相关项及安全性5个方面检测项目的参考方法和容差标准，用以保证模拟定位过程的安全性及精确性，使患者生存获益。
Abstract:
Abstract: CT simulator has the functions such as original coordination positioning and radiotherapy resetting, and it can provide image and cooridiate information for radiotherapy. Through electronic density calibration, tissue inhomogeneity correction is carried out for supporting dose calculation in treatment planning system. With reference to relevant national standards, international guidelines, clinical functions of CT simulator and the practical experience of the center, a set of acceptance and commissioning testing scheme suitable for big bore CT simulator is presented, aiming to guide and assist the newly opened department in conducting comprehensive, safe and feasible acceptance and commissioning tests. The scheme includes the reference methods and tolerance standards of CT simulator machinery, image quality, radiation dose, radiotherapy related items and safety, so as to ensure the safety and accuracy of CT simulation and survival benefits.
