Figure 12.

The ablation experiment on ‘Ra + Icp’ yielded insightful results. In cerebrovascular and airway segmentation, (a,b) showcase the comparative outcomes of ‘Ra + Icp’. Furthermore, (c) illustrates the visualization of the cerebrovascular segmentation results. The models used for evaluation include U-Net (MSFA) as the ‘Baseline + MSFA’ model, Attention U-Net (MSFA) as the ‘Baseline + MSFA + Attention’ model, and UARAI as the ‘Baseline + MSFA + Ra + Icp’ model. False positive and false negative areas are highlighted by yellow and green boxes, respectively.
