NISF++: Geometrically-grounded implicit representations of 3D+time cardiac function from 2D short- and long-axis MR views

The in-plane segmentation performance is on-par with existing CMR segmentation methods and the majority of failure cases arise from limitations in the ground-truth segmentation, for which the representations make predictions with better anatomical accuracy than its original training data are explored.

PRIME-SVR: Physics-infoRmed Implicit Multi-Echo Slice-to-Volume Reconstruction for Fetal T2 mapping

PRIME-SVR is presented, the first implicit neural representation (INR) framework for joint HR reconstruction from multi-echo MRI, which improves reconstruction sharpness, anatomical accuracy, and cross-TE structural consistency by 14%, and accelerates quantitative imaging by reducing the data needed for multi-TE recons...
