This page contains resources for RF coil design, fabrication, and testing related to the work conducted in the RF Lab of the | Magnetic Resonance Physics and Instrument Group (MR-PIGs), led by Dr. Lawrence Wald, at the A. A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Boston, MA, USA.
NEW (August 2020): Version 1 of a low-cost Mini Circuits-based RF low noise preamplifier added
NEW (March 2020): A few small bugs have been fixed on the fiber optic interface board. New versions of the board files are now available.
NEW (July 2019): Revision C of the open-source shim amplifier are now available online. Please see Current driver section below.
(JULY 2016): MATLAB code is now available for multi-coil shimming simulations. The code includes helmet-style wire patterns and a constrained optimization script for finding optimal shim currents for B0 shimming of the brain. Please see the Multi-coil B0 shimming section below.
