Compressed sensing is a promising technique for MRI reconstruction from incomplete data, but the feasibility and reliability for clinical routine applications have not been verified. Here, we present a prototypic setup that allows evaluating a recently proposed CS approach for motion-robust dynamic T1-weighted imaging in daily patient exams. It consists of a 3D stack-of-stars GRE sequence, a fully-automatic service for raw-data transfer to a multi-core server, and a highly parallelized implementation of the reconstruction algorithm. Images are saved in DICOM format and forwarded to the PACS archive, which enables our radiologists to read the images along with the conventional exams.
