In
this project, we developed improved sampling and reconstruction strategies to
provide finer temporal resolution for hyperpolarized carbon-13 3D
time-resolved MRSI with compressed sensing and multiband excitation
pulses. These improved compressed
sensing strategies better exploit the temporal redundancy. Results are shown with a 32-fold
acceleration for a 2 sec temporal resolution, 3D dynamic MRSI acquisition.
