Abstract: Highlights•An isomorphic Unet fusion model (GMRE-iUnet) for lung tumor PET and CT images is proposed.•A Hybrid CNN-Transformer feature extraction module (HCTrans) is constructed.•A residual axial attention feature compensation module (RAAFC) is proposed.•A hybrid attentional feature fusion module (HAFF) for multiscale feature information fusion is designed.
