(English Abstract)
The FOCal Underdetermined System Solver (FOCUSS) was originally designed to obtain sparse solutions from limited data. This paper adapts this algorithm for dynamic MR imaging reconstruction from angularly undersampled k-t data. FOCUSS is very effective for dynamic MR imaging such as cardiac imaging because the periodic motion is sparse on x-f space, and the initial low resolution image can be obtained from over sampled center region in k-space. Simulation results of cardiac phantom for dynamic MRI from radial k-space data prove that FOCUSS is a very powerful algorithm that reduces angular aliasing artifacts without sacrificing the resolution
