目的探讨DORADO1和DORADO4两种激光定位系统确定放射治疗患者治疗等中心的方法。方法应用激光定位系统坐标系和治疗坐标系的转换公式,基于VB软件设计TIC-CT1和TIC-CT4程序,实现最终位置的自动计算,从而确定放射治疗患者的治疗等中心。结果设计的2套程序均能实现安全登陆、坐标值自动转换、查错和生成报告等功能。方便放射治疗工作人员快速精确地确定患者治疗等中心,并保存相关的患者治疗信息。结论该程序具有良好的临床应用价值,可节约工作人员的计算时间,提高工作效率。
Objective To investigate the methods of determining the treatment center of radiation therapy patients by DORADO1 and DORADO4 laser positioning systems. Methods The conversion formulas of laser positioning system coordinate system and treatment coordinate system were applied. The TIC-CT1 and TIC-CT4 programs were designed based on VB software to automatically calculate the final position and determine the treatment center for radiotherapy patients. The results of the design of the two sets of programs can achieve safety landing, automatic conversion of coordinates, check and generate reports and other functions. Convenient radiotherapy staff to quickly and accurately determine the patient treatment center, and save the relevant patient treatment information. Conclusion The program has good clinical value, saving staff time and improve work efficiency.
