【摘要】 等剂量曲线的跟踪和绘制是放射物理剂量学中的一个基本！司题。本文描述了一种逐行逐列扫描式等剂量曲线的跟踪和绘制算法。它具有思路简捷、占用内存少、程序移植性强、绘图区域边界判断简单及适用于任意形状的封闭区域等优点。该方法也适用于其它等值线的跟踪和绘制。更多还原

【Abstract】 Search and plot isodose curve is a one of foundation study in radiation dosimetry. In this pa-per,we introduce a new method for search and plot isodose curve by scan row and column one by one. There aremany adavantages such as uncomplicated,need less memory,simple determine border way and fit to any shapedregion. In addition,the method can suit to search and plot the other isopleth curves.更多还原
