New 3D mesh refinement improves pericardium segmentation in cardiac CT scans

Researchers have developed a novel 3D iterative mesh refinement framework to improve the segmentation of the pericardium in cardiac CT scans. This method utilizes anatomical context and inherent anatomical rules, rather than solely relying on image gradients, to refine initial segmentations into precise and anatomically plausible results. The framework is designed as a model-agnostic post-processing step, demonstrated to enhance segmentation metrics on both in-house and open-source datasets, particularly when applied to weaker initial segmentations. It is formulated as a gradient-based, GPU-accelerated system that can be extended to other anatomical segmentation tasks. AI
