DiffuseMorph: Unsupervised Deformable Image Registration Using Diffusion Model. (arXiv:2112.05149v2 [eess.IV] UPDATED)

Deformable image registration is one of the fundamental tasks in medical
imaging. Classical registration algorithms usually require a high computational
cost for iterative optimizations. Although deep-learning-based methods have
been developed for fast image registration, it is still challenging to obtain
realistic continuous deformations from a moving image to a fixed image with
less topological folding problem. To address this, here we present a novel
diffusion-model-based image registration method, called DiffuseMorph.
DiffuseMorph not only generates synthetic deformed images through reverse
