摘要
针对目前治疗计划系统的缺陷,提出了一种基于二维定位图像的射野剂量自动计算的设计方法和步骤。着重探讨了系统的实现技术,包括空间坐标变换、射野剂量分布的数据表达、定位图像预处理、射野边缘检测与提取和任意点的剂量计算等。
According to the deficiencies of the present treatment planning systems, a research of field size dosage calculation based on two-dimensional localization image is presented. The technologies are emphasized including coordinate transformation, image preprocessing, edge detection ＆ extraction and field size dosage calculation, etc.
