Title (EN) RF SHIMMING WITH RF POWER REGULARIZATION USING A MULTI-CHANNEL RF TRANSMIT SYSTEM FOR MRI
(FR) CALAGE RF AVEC RÉGULARISATION DE PUISSANCE RF À L’AIDE D’UN SYSTÈME DE TRANSMISSION RF À CANAUX MULTIPLES POUR IRM
Abstract: front page image
(EN)A magnetic resonance system comprises: a magnetic resonance scanner (12) including a multi-channel RF transmit system (32, 34); an RF shimming processor (50) configured to compute complex amplitude values for operative channels of the multi-channel RF transmit system based on a figure-of-merit (70) comprising a weighted combination of a B1 uniformity measure and a total power measure; and an RF transmit sub-system (30) configured to drive the multi-channel RF transmit system to excite magnetic resonance using the complex amplitude values computed by the RF shimming processor for the operative channels of the multi-channel RF transmit system.
