APPARATUS AND METHOD FOR DYNAMICALLY AND/OR LOCALLY ADJUSTING TRANSMIT GAIN AND RF SHIMMING DURING IMAGING AND SPECTROSCOPY

摘要

An apparatus that includes an image processor that is configured to acquire a multi-slice B1 map during a pre-scan of a target object; calculate a plurality of B1 values each corresponding to one slice of the multi-slice B1 map; and adjust transmit gain for each slice of a scan of the target object, according to the B1 value or values calculated for that slice.
