Real-time 4D MRI reconstruction using DVR-NeMF, a framework for dynamic volumetric reconstruction.

ABSTRACT: In this study, four dynamic magnetic resonance imaging (MRI) sequences were first developed to collect data. On this basis, we presented DVR-NeMF, a neural magnetic field framework that enables real-time, high-dimensional (4D) MRI reconstruction from synchronized dynamic 2D image slices and physiological signals. By embedding spatiotemporal priors into an implicit representation of the imaging space, DVR-NeMF reconstructs temporally consistent 3D volumes over time with high anatomical fidelity. Comprehensive evaluations across a cardiovascular phantom, cardiac dynamic bio-simulators, and living human hearts, including external out-of-distribution validation on the Automated Cardiac Diagnosis Challenge (ACDC) dataset, demonstrated that DVR-NeMF outperforms both autoencoder- and generative a
