Researchers have developed a new U-Net architecture called AC2RUNet to improve the segmentation of the Circle of Willis from MRA scans. This model addresses challenges posed by complex vascular topology and fragmentation, which often lead to broken vessel artifacts in standard CNNs. AC2RUNet employs a two-stream approach, separating static anatomical feature extraction from dynamic topological error refinement, and utilizes a curriculum learning strategy for better topological connectivity.
