Constrained image reconstruction and spin tagging techniques for functional MR imaging
Magnetic Resonance Imaging (MRI) holds enormous potential for exploring the functional centers of a living brain in vivo. Among the MRI techniques a number of different approaches have provided initial success. The focus of this work is on applications of constrained image processing techniques for …
