我们参与了BIC-MAC挑战赛,采用基于多模态3D块的U-Net从NAC-PET、MRI和2D顶图生成伪CT。通过使用独立的PET和MR编码器、多尺度特征融合,以及在瓶颈处采用基于FiLM的顶图条件化,我们得到了一个整合互补跨模态信息同时减少对模态间精确体素级对应依赖的模型。我们的最终提交可在此处获取:this https URL
英文摘要
We participated in the BIC-MAC Challenge with a multimodal 3D patch-based U-Net for pseudo-CT generation from NAC-PET, MRI, and 2D topograms. By using separate PET and MR encoders, multi-scale feature fusion, and FiLM-based topogram conditioning at the bottleneck, we obtain a model that integrates complementary cross-modal information while reducing reliance on precise voxel-wise correspondence between modalities.
