An Extended Phase Graph-based framework for DANTE-SPACE simulations including physiological, temporal, and spatial variations
Matthijs H. S. de Buck, Peter Jezzard, Aaron T. Hess
Purpose: The DANTE-SPACE sequence facilitates three-dimensional intracranial vessel wall imaging with simultaneous suppression of blood and cerebrospinal fluid (CSF). However, the…

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…

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-…
