Mutual information neural estimation for unsupervised multi-modal registration of brain images. (arXiv:2201.10305v1 [eess.IV])

Many applications in image-guided surgery and therapy require fast and
reliable non-linear, multi-modal image registration. Recently proposed
unsupervised deep learning-based registration methods have demonstrated
superior performance compared to iterative methods in just a fraction of the
time. Most of the learning-based methods have focused on mono-modal image
registration. The extension to multi-modal registration depends on the use of
an appropriate similarity function, such as the mutual information (MI). We
propose guiding the training of a deep learning-based registration method with …
