Figure 5:

Example text files output by Shimming Toolbox. A) Text file to be read by an Arduino Teensy board in the case of custom shim coils during B0 dynamic shimming (13). The slices were acquired in an interleaved fashion and are chronologically written to the text file. Each row corresponds to a slice and each column a coil channel. B) Text file to be read by the pulse sequence during B0 real-time dynamic shimming. Each block of three rows corresponds to a slice and within that block, a static coefficient, real-time coefficient and mean pressure are provided. C) Text file with B1+ static shimming coefficients where each row is a transmit channel and the columns are the magnitude and phase coefficients.
