Researchers have developed Anatomy-Informed Neural Networks (AINN) to address limitations in deep learning models for anatomical predictions, particularly when training data is scarce. AINN incorporates soft anatomic priors as penalty terms in the loss function and hard priors directly into the network architecture, ensuring anatomically impossible predictions are avoided by design. The approach was demonstrated on a clinical test case involving guidewire-induced aortoiliac deformation, lifting vessel centerlines and wire paths into a Lie group SE(3) framework and coupling a Cosserat-rod wire to an anatomically anchored vessel. A Wasserstein-2 optimal-transport loss was used for supervision, enabling 3D predictions from 2D angiograms, though the mechanics solver and mesh convergence require further development. AI
