Abstract
A controller that is operatively connected with a magnet assembly, which defines a target volume; and an image processor, which is configured to obtain calibration data from the controller; map B1 transmit intensity from the magnet assembly to the target volume, based on the calibration data; calculate a B1 transmit shading correction based at least on the map of B1 transmit intensity and on pulse sequence parameters; obtain k-space data of an imaging subject within the target volume from the controller operating the magnet assembly based on the pulse sequence parameters; develop an MR image from the k-space data; and apply the B1 transmit shading correction to the MR image.
