摘　　要：目的:研究一种辅助正电子发射断层扫描-CT(PET-CT)技师进行摆位的系统,减少技师操作中所受辐射剂量,实现精准摆位,提高检查效率。方法:对比现有的PET-CT技师摆位方式,通过远程控制子系统控制PET-CT操控面板,代替技师进入PET-CT机房,减少技师与PET-CT受检者接触,并利用受检者位姿可视化子系统对受检者进行标准摆位。结果:辅助PET-CT技师摆位系统的应用,能够在最大程度地减少技师所受辐射剂量的同时实现对受检者进行精准摆位,避免重复扫描,节省时间,提高检查效率。结论:辅助PET-CT技师摆位系统可以减少技师所受辐射,提高摆位精度,具有一定的临床使用价值。Objective： To study a position system for assisting positron-emission tomography PET-CT technologists so as to reduce the received radiation dose of technologist, achieve precisely position and enhance the efficiency of examination. Methods： Compared to the current method of PET-CT technologist, the new method controlled the operative panel of PET-CT through remote controlling subsystem, and it substituted the operation of technologist in PET-CT room. This method could reduce the touch between the technologist and patient received cure of PET-CT and its posture visualization subsystem positioned the standard place for patient. Results： The system could reduce the received radiation dose of technologist at the greatest extent, and it could realize the precise position for the patients, avoid repetitive scan, save time and increase the efficiency of inspection. Conclusion： The position system for assisting technologist can reduce the received radiation of the technologist and increase the precision of the placement. It is worthy to be used in clinical practice and be generalized.
