基于图像间平移的MRI体分割和分类的无监督域自适应

Unsupervised Domain Adaptation for MRI Volume Segmentation and Classification Using Image-to-Image Translation

Satoshi Kondo, Satoshi Kasai

摘要:

无监督域自适应是一种域自适应,它利用来自源域的标记数据和来自目标域的未标记数据。在医学图像分割的跨模态域适应挑战(crossMoDA 2022)中,提供了脑部的对比增强T1 MRI体积作为源域数据,并提供了高分辨率T2 MRI体积作为目标域数据。crossMoDA 2022挑战包含两个任务,前庭神经鞘瘤(VS)和耳蜗的分割,以及VS与Koos分级的分类。在本报告中,我们介绍了我们针对crossMoDA 2022挑战的解决方案。我们采用图像到图像的翻译方法进行无监督的域自适应和剩余的U网分割任务。我们使用SVM进行分类任务。实验结果表明,对于分割任务,平均DSC和ASSD分别为0.614和2.936,对于分类任务,MA-MAE为0.84。

英文摘要:

Unsupervised domain adaptation is a type of domain adaptation and exploits labeled data from the source domain and unlabeled data from the target one. In the Cross-Modality Domain Adaptation for Medical Image Segmenta-tion challenge (crossMoDA2022), contrast enhanced T1 MRI volumes for brain are provided as the source domain data, and high-resolution T2 MRI volumes are provided as the target domain data. The crossMoDA2022 challenge contains two tasks, segmentation of vestibular schwannoma (VS) and cochlea, and clas-sification of VS with Koos grade. In this report, we presented our solution for the crossMoDA2022 challenge. We employ an image-to-image translation method for unsupervised domain adaptation and residual U-Net the segmenta-tion task. We use SVM for the classification task. The experimental results show that the mean DSC and ASSD are 0.614 and 2.936 for the segmentation task and MA-MAE is 0.84 for the classification task.
