摘要: 针对放射治疗计划系统GyroRTPS需要,给出了一个放射线剂量分布三维可视化的实现方法,以帮助医师多角度查看病灶组织任意剖面上的放射线剂量分布情况。首先论述系统中对体数据和剂量数据的坐标变换、插值计算等预处理;然后根据VTK工具包中可处理的数据类型对数据进行转换,给出了基于VTK实现剂量分布三维显示及其与体数据融合显示的方法。实例测试结果和临床使用表明,基于该方法开发的软件系统运行可靠,可更好地辅助医师进行放射治疗决策。

Abstract: According to the requirements of GyroRTPS, a 3D visualization method used to display the distribution of radiotherapy dose was proposed to assist doctors to look over the dose distribution from different angles. Firstly, some preprocesses of coordinate transformation and interpolation on volume data and dosage data were discussed. Secondly, after these processing, the data for visualization was normalized according to VTK specifications. Finally, the method based on VTK to joint display dose data and human body data in 3D way was realized. The test shows that the reliability of this method and this system can better help the doctor carry on the radiotherapy.
