A neighborhood attention transformer network for enhanced 3D segmentation of the left anterior descending artery.
BACKGROUND Accurate segmentation of the left anterior descending (LAD) artery in 3D free-breathing, non-contrast CT is critical for cardiac dose sparing in thoracic radiotherapy. The task is inherently difficult because the LAD is extremely small, exhibits poor soft-tissue contrast, and varies substantially across pati...
