Towards Foundation Models Learned from Anatomy in Medical Imaging via Self-Supervision

1 code implementation27 Sep 2023 Mohammad Reza Hosseinzadeh Taher, Michael B. Gotway, Jianming Liang

Human anatomy is the foundation of medical imaging and boasts one striking characteristic: its hierarchy in nature, exhibiting two intrinsic properties: (1) locality: each anatomical structure is morphologically distinct from the others; and (2) compositionality: each anatomical structure is an integrated part of a larger whole.
