Gradient Nonlinearity-Corrected 4D MRI for Abdominal Motion Quantification on a 1.5T MR-Linac
Motion-resolved 4D MRI is essential for assessing abdominal tumor and organ motion, but gradient nonlinearity (GNL) causes geometric distortion that reduces spatial fidelity and motion accuracy. This study evaluates GNL correction for 4D MRI on a 1.5T MR Lina...

Low-Distortion and High-SNR Diffusion-Weighted MRI on an MR-Linac with Spiral Readouts
Conventional diffusion-weighted MRI (DWI) uses single-shot echo planar imaging (ssEPI), which is highly susceptible to geometric distortion, limiting its use for radiotherapy guidance on MR-LINAC systems. Turbo-spin-echo (TSE) and multi-shot EPI (msEPI) DWI r...

A Dynamic Reconstruction and Motion Estimation Framework for Gaussian Representation-Based Time-Resolved Volumetric MR Imaging (DREME-GSMR)
Time-resolved volumetric MRI reconstructed from minimal k-space samples is critical for motion-adaptive radiotherapy to capture real-time deformable motion. We propose a Gaussian representation-based one-shot learning framework that models patient anatomy and...
