论文摘要
语义细分是医学图像计算中最受欢迎的研究领域之一。也许令人惊讶的是，尽管它可以追溯到2018年，但NNU-NET仍在为各种细分问题提供竞争性的解决方案，并定期用作挑战挑战算法的开发框架。在这里，我们使用NNU-NET参与AMOS2022挑战，该挑战带有一组独特的任务：数据集不仅是有史以来最大的最大的任务，并拥有15个目标结构，而且竞争还需要提交的解决方案来处理MRI和CT扫描。通过仔细修改NNU-NET的超参数，在编码器中添加残差连接以及设计自定义后处理策略，我们能够在NNU-NET基线上实质上改进。我们的最终合奏在任务1（CT）的骰子得分为90.13，而任务2（CT+MRI）的骰子得分为89.06，在提供的培训案例中进行了5倍的交叉验证。
Semantic segmentation is one of the most popular research areas in medical image computing. Perhaps surprisingly, despite its conceptualization dating back to 2018, nnU-Net continues to provide competitive out-of-the-box solutions for a broad variety of segmentation problems and is regularly used as a development framework for challenge-winning algorithms. Here we use nnU-Net to participate in the AMOS2022 challenge, which comes with a unique set of tasks: not only is the dataset one of the largest ever created and boasts 15 target structures, but the competition also requires submitted solutions to handle both MRI and CT scans. Through careful modification of nnU-net's hyperparameters, the addition of residual connections in the encoder and the design of a custom postprocessing strategy, we were able to substantially improve upon the nnU-Net baseline. Our final ensemble achieves Dice scores of 90.13 for Task 1 (CT) and 89.06 for Task 2 (CT+MRI) in a 5-fold cross-validation on the provided training cases.
