Universal RF shimming is a proven method to avoid the time-consuming process of calculating patient-specific RF shims for every individual subject. Nevertheless, this method requires numerous B1+ maps from in vivo measurements, which is a time-consuming process, especially in the context of product development. This work therefore investigates whether a universal RF shim based on simulated B1+ maps, which are needed for the safety assessment of the coil anyways, is a viable alternative compared to shim optimization based on in vivo data. The study was performed using a torso coil at 7T for the prostate and cardiac region.
