New methods improve cardiac motion estimation with implicit neural representations

Researchers have explored four distinct strategies for learning cardiac motion priors to enhance the efficiency and accuracy of implicit neural representations (INRs) in cardiac motion estimation. These strategies, including a population prior, a consensus prior, auto-decoders, and meta-learning, were evaluated using cardiac MRI data from the UK Biobank. The findings indicate that all learned priors significantly improve early adaptation performance compared to random initialization, with meta-learning demonstrating the best overall adaptation trajectory over 50 iterations.
