An Efficient Algorithm for Dynamic MRI Using Low-Rank and Total Variation Regularizations

Dynamic magnetic resonance imaging (dMRI) is an important medical imaging technique that has been widely used for multiple clinical applications. However, dynamic MRI is inherently a very slow process due to a combination of different constraints such as nuclear relaxation times and peripheral nerve stimulation. Since the speed of acquisition in dynamic MRI has physical limits, there exists a trade-off between temporal and spatial resolution. Additionally, long scan durations can make patient uncomfortable and also increase the chance of motion artifacts.
