Extended Data Fig. 1. Sound pressure levels.

Extended Data Fig. 1

Measured using a high-resolution EPI sequence using two gradient strengths, typically used for neuroimaging studies, at a range of echo spacings using three orthogonal readout directions, and showed sound levels within prescribed safety limits ( < 99 dB) when using 33 dB attenuation earplugs. (*)Approximate dB measures at 0.55 ms echo spacing (E/S) due to sound meter clipping and HF 76 did not run at 0.55 ms E/S due to stimulation warning.
