Traumatic abdominal injury can lead to multiple complications including laceration of major organs such as kidneys. Contrast-enhanced Computed Tomography (CT) is the primary imaging modality for evaluating kidney injury. However, the traditional visual examination of CT scans is time consuming, non-quantitative, prone to human error, and costly. In this work we propose a kidney segmentation method using machine learning and active contour modeling. We first detect an initialization mask inside the kidney and then evolve its boundary. This model is specifically developed and evaluated on trauma cases. Our experimental results show the average recall score of 92.6% and average Dice similarity value of 88.9%.
创伤性腹部损伤可导致多种并发症，包括肾脏等主要器官的撕裂伤。对比增强计算机断层扫描（CT）是评估肾脏损伤的主要成像方式。然而，传统的CT扫描视觉检查耗时、非定量、容易出现人为误差且成本高昂。在这项工作中，我们提出了一种使用机器学习和主动轮廓模型的肾脏分割方法。我们首先在肾脏内部检测一个初始化掩码，然后演化其边界。该模型是专门针对创伤病例开发和评估的。我们的实验结果显示平均召回率为92.6%，平均骰子相似性值为88.9%。
