Dual-Part Multi-Lateral Branched Network for Multi-Class Segmentation in Cardiovascular Catheterization Angiograms
Read the original on arXiv AI →The paper introduces Dual-Part MLBNet, a multi-lateral branched network designed for fast, accurate, and explainable multi-class segmentation of cardiovascular catheterization angiograms. The architecture uses multi-lateral encoder blocks for diverse feature extraction and multi-head decoder branches that specialize in different structural properties, enabling simultaneous segmentation of guidewire, catheter, vessels, and background. Experiments on phantom, synthetic human-simulated aorta, and animal model angiograms demonstrate high overall accuracy and effective separation of foreground structures from background.
