Figure 1. Workflow overview of automatic vessel segmentation. Step 1: Dual-view maximum intensity projection (MIP) annotation is performed using axial and coronal MIP planes to reconstruct the perforator vessel paths with improved spatial consistency. Step 2: An anatomically aware region of interest (ROI) is cropped and individually adapted for each patient to precisely target the expected anatomical location of the perforators. Step 3: The vascular tree within the defined ROI is automatically segmented using a deep-learning model.
