临床正常组织效应的定量分析

三维适形放疗常规分割

注：“心包体积”是指在心脏轮廓的“外皮”，人工绘制的心脏体积用作外边界，内边界使用自动勾画将外边界内缩1 cm，将连续轴位CT片上的心包轮廓线网格化为三维结构。

Conventional fractionated 3D-CRT

Note: The “pericardium volume” was defined as a “rind” within the previously contoured heart volumes. The manually contoured heart volumes served as the outer border, and the inner border was automatically contoured 1 cm within these same contours using the planning. The heart pericardium contours on successive axial CT slices were meshed into a 3D structure.
