Unsupervised Multi-Modal Medical Image Registration via Discriminator-Free Image-to-Image Translation

IJCAI 2022poster

In clinical practice, well-aligned multi-modal images, such as Magnetic Resonance (MR) and Computed Tomography (CT), together can provide complementary information for image-guided therapies. Multi-modal image registration is essential for the accurate alignment of these multi-modal images. However,…
