Unsupervised Adaptation from FDG to PSMA PET/CT for 3D Lesion Detection under Label Shift

Xiaofeng Liu, Menghua Xia, Yanis Chemli +3

In this work, we propose an unsupervised domain adaptation (UDA) framework for 3D volumetric lesion detection that adapts a detector trained on labeled FDG PET/CT to unlabeled PSMA…
