We devise a novel self-supervised learning (SSL) framework that underpins the development of powerful models foundational to medical imaging via learning anatomy. Our framework not only generates highly generalizable pretrained models, called Adam (autodidactic dense anatomical models), but also, in contrast to existing SSL methods, yields dense anatomical embeddings, nicknamed Eve (embedding vectors), preserveing a semantic balance of anatomical diversity and harmony, making them semantically meaningful for anatomy understanding.
