Cardiac CT Anatomical Segmentation Dataset Develop

The National Institutes of Health National Heart, Lung and Blood Institute seeks expert manual annotation of 235 contrast-enhanced cardiac CT imaging studies to create a cardiovascular segmentation dataset, with responses due September 10, 2026 at 3:00 PM EDT.
