Achieving a desired RF transmit field ( B1+ ) in small regions of interest is critical for single‐voxel MRS at ultrahigh field. Radio‐frequency (RF) shimming, using parallel transmission, requires B1+ mapping and optimization, which limits its ease of use. This work aimed to generate calibration‐free RF shims for predefined target regions of interest, which can be applied to any participant, to produce a desired absolute magnitude B1+ (| B1+ |).
