多部位肿瘤适形放疗 CT 定位扫描技术的探讨及其临床意义 【摘 要】 目的:探讨适形放疗中 CT模拟三维定位扫描技术及其应用价值
治疗与方法:回顾分析 620 例体颈头部多种肿瘤的 CT 模拟三维定位技术及其应用,体位固定方式:框架定位与激光定位技术
结果:CT 模拟过程在 CT 重建图像上进行,CT 扫描能精确确定计划靶区
注意 CT 扫描参数的掌握,数据的精确采集,CT 值的测定等能满足适形放疗的需要
结论:CT 模拟定位在适形放疗中有重要价值
【关键词】:肿瘤;CT 模拟定位;适形放疗[Abstract] objective: To study CT scanning technique and the application of simulative three-dimensional treatment plan system (3DTPS) in conformal therapy
Materiates and Methods: We reviewed CT simulation 3-D orientation and its application in 620 cases of tumor of body, neck and head, the fixation mode including frame and laser light orientation
Result: The course of CT simulation was carried on the reconstructed imaging, the target was exactly confirmed by CT scan, choose suitable parameter, collect exact data and measure CT were important t
