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.
