Scan-Adaptive MRI Undersampling Using Neighbor-based Optimization (SUNO)
SUNO learns per-scan adaptive k-space undersampling patterns via ICD optimization and NN lookup from low-frequency data, showing better reconstruction quality than standard patterns at 4x and 8x acceleration on fastMRI knee and brain data.
