Abstract

In this work we tabulate and histogram the image segmentation time for beam's eye view (BEV) treatment planning in our center. The average time needed to generate contours on CT images delineating normal structures and treatment target volumes is calculated using a data base containing over 500 patients' BEV plans. The average number of contours and total image segmentation time needed for BEV plans in three common treatment sites, namely, head/neck, lung/chest, and prostate, were estimated.

摘要

在这项工作中，我们将本中心射野方向观（BEV）治疗计划的图像分割时间制成表格并绘制直方图。使用包含500多名患者BEV计划的数据库，计算在CT图像上生成描绘正常结构和治疗靶区体积的轮廓所需的平均时间。估算了三个常见治疗部位（即头颈部、肺部/胸部和前列腺）的BEV计划所需的平均轮廓数和总图像分割时间。
