A method of measuring transmit (micro-) coil profile (B1) distribution is presented. In as much as it does not use spatial encoding, it reaches fine resolution in B1 at very high signal-to-noise ratios. The procedure can be used to alleviate systematic errors in spectroscopic data analysis caused by transmit field non-uniformity or can be employed for a quick evaluation of transmit (micro-) coil performance.
