From: SALT: Introducing a framework for hierarchical segmentations in medical imaging using label trees
Example of a hierarchical segmentation. (A) In the thorax, the biggest region is the thoracic cavity. (B) The thoracic cavity can then be subdivided into lungs and mediastinum. (C) The mediastinum has a further subregion the pericardium, and the lungs can be subdivided into lower/middle/upper left/right lobes. (D) The pericardium contains the heart, which can be subdivided into myocardium and left/right ventricle/atrium. The full segmentations originate from the TotalSegmentator, while the sparse segmentations are from SAROS.
