基于图谱的自动分割（ABS）算法有可能减少体积描绘的变异性。几家供应商提供的软件主要用于颅骨、头颈部和前列腺病例。本研究将比较放射肿瘤学家产生的轮廓与前列腺床病例（包括股骨头、膀胱和直肠）的不同自动ABS算法计算的轮廓。轮廓比较通过不同的指标进行评价，如体积比，Dice系数和Hausdorff距离。取决于感兴趣体积的结果显示不同软件之间存在一些差异。自动轮廓可以是描绘器官的一个很好的起点，因为不同的供应商提供了有效的编辑工具。它应该成为一个重要的帮助，在未来几年的危险器官划定。
Automated atlas-based segmentation (ABS) algorithms present the potential to reduce the variability in volume delineation. Several vendors offer software that are mainly used for cranial, head and neck, and prostate cases. The present study will compare the contours produced by a radiation oncologist to the contours computed by different automated ABS algorithms for prostate bed cases, including femoral heads, bladder, and rectum. Contour comparison was evaluated by different metrics such as volume ratio, Dice coefficient, and Hausdorff distance. Results depended on the volume of interest showed some discrepancies between the different software. Automatic contours could be a good starting point for the delineation of organs since efficient editing tools are provided by different vendors. It should become an important help in the next few years for organ at risk delineation.
