A. A. Martinos Center / MIT parallel transmission Wiki

Example of a pTx RF spiral pulse result

This Wiki is a resource for people interested in parallel transmission, especially RF pulse design and electromagnetic simulation, developed by Larry Wald's group at the A. A. Martinos Center for Biomedical Imaging, Elfar Adalsteinsson's group at MIT and Luca Daniel and Jacob White group at MIT.

pTx pulse design code

• Small flip-angle spokes with explicit SAR constraints (Bastien Guerin)
• SMS spoke pulse design with explicit SAR constraints (Bastien Guerin)
• Joint RF & gradient waveform optimization for inner-volume excitation (Mathias Davids)
• B0/B1+ spoke design algorithm for joint flip-angle and through-slice dephasing mitigation (Bastien Guerin)

MRI / deep brain stimulation / implants safety code

• Matlab-based temperature solver (Bastien Guerin)
• Matlab-based code for topology correction of DBS path extracted from CT data (Bastien Guerin)

Ultimate SNR code

• Computation of ultimate basis-sets in realistic body models
