New MRI Technique Corrects Distortions Using Gaussian Primitives

Researchers have developed a new physics-informed framework for correcting geometric distortions in diffusion MRI data. This method jointly estimates the magnetic field (B0) and distortion-free images directly from k-space data, bypassing the need for intermediate reconstruction steps that can introduce artifacts. By representing images and B0 fields as Gaussian primitives and utilizing rotated-view EPI acquisitions, the framework improves accuracy, especially at high b-values and acceleration factors, outperforming sequential correction methods.
