Accelerated calibrationless parallel transmit mapping using joint transmit and receive low-rank tensor completion
Aaron T Hess, Iulius Dragonu, Mark Chiew
Purpose: To evaluate an algorithm for calibrationless parallel imaging to reconstruct undersampled parallel transmit field maps for the body and brain. Methods: Using synthetic dat…

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-…

Approximate Message Passing with a Colored Aliasing Model for Variable Density Fourier Sampled Images
Charles Millard, Aaron T Hess, Boris Mailhé +1
The Approximate Message Passing (AMP) algorithm efficiently reconstructs signals which have been sampled with large i.i.d. sub-Gaussian sensing matrices. Central to AMP is its "sta…
