MT‐weighted data points are given as effective flip angle and offset frequency pairs. Pulse duration and pulse gap are the same for the two protocols (15 ms/15 ms), whereas pulse train lengths are different (N = 50 for the uniform protocol to achieve steady‐state conditions as in previous qMT studies, N = 25 for the optimal protocol). The MT pulse shape is sinc‐Gaussian with no lobes.
