Head-and-neck multi-channel B1+ mapping and carotid arteries RF shimming using a parallel transmit head coil
Matthijs H. S. de Buck, Peter Jezzard, Aaron T. Hess
Purpose: Neurovascular MRI suffers from a rapid drop in B1+ into the neck when using transmit head coils at 7T. One solution to improving B1+ magnitude in the major feeding arterie…

Tuning-free multi-coil compressed sensing MRI with Parallel Variable Density Approximate Message Passing (P-VDAMP)
Charles Millard, Mark Chiew, Jared Tanner +2
Magnetic Resonance Imaging (MRI) has excellent soft tissue contrast but is hindered by an inherently slow data acquisition process. Compressed sensing, which reconstructs sparse si…
