Compressed Sensing Coronary MRI Sequence

Technology No. 20170287

Higher Acceleration Rates than Parallel Imaging

A novel MRI (Magnetic Resonance Imaging) imaging sequence and reconstruction method uses a randomly undersampled acquisition of a 3D k-space to allow a compressed sensing accelerated coronary MRI sequence. Compressed sensing allows for acceleration rates higher than parallel imaging.

Coronary MRI still faces major challenges, including lengthy acquisition time, low signal-to-noise-ratio (SNR), and suboptimal spatial resolution. Higher spatial resolution in the sub-millimeter (sub-mm) range is desirable, but this results in increased acquisition time and lower SNR, hindering its clinical implementation.
