Synopsis

Keywords: Safety, Gradients, Acoustic Measurement, ZTE, 3D Radial, SilentThis abstract aims to provide a general method of measuring the acoustic noise produced by a scanning protocol and to present the acoustic differences in absolute sound pressure level. To demonstrate these methods we show results using conventional Cartesian and acoustically quieter ZTE based protocols on 3T and 7T systems.
