Correlation-aware Coarse-to-fine MLPs for Deformable Medical Image Registration

CVPR 2024poster

Deformable image registration is a fundamental step for medical image analysis. Recently transformers have been used for registration and outperformed Convolutional Neural Networks (CNNs). Transformers can capture long-range dependence among image features which have been shown beneficial for regist…

A Spatiotemporal Volumetric Interpolation Network for 4D Dynamic Medical Image

CVPR 2020poster

Dynamic medical images are often limited in its application due to the large radiation doses and longer image scanning and reconstruction times. Existing methods attempt to reduce the volume samples in the dynamic sequence by interpolating the volumes between the acquired samples. However, these met…
