Data and code associated with the publication: Phase contrast coronary blood velocity mapping with both high temporal and spatial resolution using triggered Golden Angle rotated Spiral k-t Sparse Parallel imaging (GASSP) with shifted binning

This work proposes a novel MRI method to measure blood flow and vessel cross-sectional area of the coronary arteries with a higher temporal and spatial resolution compared to currently available methods. The proposed methods includes both a new MRI acquisition method using a triggered golden angle (GA) scheme and a k-t sparse parallel imaging reconstruction algorithm that uses shifted binning that minimizes gaps in k-space to improve image quality. The method is tested in the right coronary artery (RCA) and the left anterior descending (LAD) artery of eight healthy subjects in an IRB approved study, and compared against current methods that have either high spatial or high temporal (but not both) resolutions.
