Researchers have developed GSMR3D, a novel 3D MRI super-resolution model capable of reconstructing images at arbitrary isotropic and anisotropic resolutions from a single checkpoint. This model utilizes a learned dictionary of anisotropic 3D Gaussian prototypes, scale-conditioned frequency encoding, and an exact measurement-consistency projection to ensure reconstructions align with the acquired low-resolution data. Trained on over 30,000 T1-weighted brain MRI volumes, GSMR3D demonstrates superior performance in reconstruction quality and downstream tasks like tumor segmentation and lesion detection compared to geometry-specific methods, while significantly reducing MRI acquisition time.
