AltGDmin for Accelerated L+S Dynamic MRI

In our research, we present a new method, altGDmin-MRI-L+S, for faster dynamic MRI. This technique assumes a model where the image sequence can be represented as a sum of low-rank (LR) and sparse (S) elements. While this LR+S model is widely used in MRI, our innovation lies in creating an efficient and accurate algorithm. Unlike other methods, ours doesn't require specific adjustments for different MRI scenarios, sampling rates, or methods. We've proven that our method performs better, on average, through tests on eight diverse dynamic MRI applications with varying sampling rates and methods, outperforming existing approaches.
