随着深度学习的快速发展,nnUNet等先进架构在医学影像分割任务中展现出强大的实力。本文将指导读者如何使用BraTS 2020数据集训练nnUNet模型,并对比多模态与单模态训练的差异和效果。 1. 数据准备: BraTS 2020数据集包含了多模态的MRI扫描图像,包括T1、T1c、T2、FLAIR四种模态。在训练前,需要对数据进行预处理,如标准化...
BraTS 2020 分割任务前3名 冠军团队来自德国癌症研究中心,文章链接如下 方法基于nnU-Net,主要改动如下: 基于区域的训练(Region-based training): BraTS分割的目标有三类:enhancing tumor,tumor core, and whole tumor,然而在计算这几类分割指标的时候区域是有重叠的,比如whole tumor就是下图中绿色+红色+蓝色合并到一...

To this end, we trained multiple U-net like neural networks, mainly with deep supervision and stochastic weight averaging, on the Multimodal Brain Tumor Segmentation Challenge (BraTS) 2020 training dataset, in a cross-validated fashion. Final brain tumor segmentations were produced by first ...

我们进一步对 QU-BraTS 2020 的 14 个独立参与团队产生的分割不确定性进行了基准测试,所有这些团队也都参与了主要的 BraTS 分割任务。总的来说,我们的研究结果证实了不确定性估计为分割算法提供的重要性和补充价值,因此强调了医学图像分析中不确定性量化的必要性。我们的评估代码在此 https URL 上公开可用。
