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…

Optimization of Undersampling Parameters for 3D Intracranial Compressed Sensing MR Angiography at 7 Tesla
Matthijs H. S. de Buck, Peter Jezzard, Aaron T. Hess
Purpose: 3D Time-of-flight (TOF) MR Angiography (MRA) can accurately visualize the intracranial vasculature, but is limited by long acquisition times. Compressed sensing (CS) recon…

An investigation into the minimum number of tissue groups required for 7T in-silico parallel transmit electromagnetic safety simulations in the human head
Matthijs H. S. de Buck, Peter Jezzard, Hongbae Jeong +1
Purpose: Safety limits for the permitted Specific Absorption Rate (SAR) place restrictions on pulse sequence design, especially at ultra-high fields ( tesla). Due to inter-…
