摘要
本文提出一种在近距离放射治疗计划中绘制等剂量曲线的方法,该方法是网格法的一种改进算法,无需求解两条直线间的交点,简化了计算量,同时根据近距离治疗中剂量分布的特点,简化了起点的寻找,在应用中取得良好的效果。
An improving method, named direction-coding, is presented in this paper for plotting isodose curves in brachyther-apy treatment planning. It is not necessary to find solutions of the intersection point of two lines and distance between two points. All possible curves can be searched with the simplified algorithm. The method is well applied in brachytherapy treatment planning.
