Anatomically plausible image registration often requires volumetric preservation. Previous approaches to incompressible image registration have exploited relaxed constraints, ad hoc optimization methods or practically intractable computational schemes. Divergence-free velocity fields have been used to achieve incompressibility in the continuous domain, although, after discretization, no guarantees have been provided. During this talk, Lucas will introduce stationary velocity fields (SVFs) parameterized by divergence-conforming B-splines in the context of image registration and show how we can use them to impose incompressibility with theoretical guarantees.
