Abstract
A magnetic resonance imaging (MRI) apparatus includes a magnetic resonance imaging (MRI) system having a plurality of gradient coils positioned about a bore of a magnet, and an RF transceiver system and an RF switch controlled by a pulse module to transmit RF signals to an RF coil assembly to acquire MR images, and a computer programmed to generate an original image of an object, generate a proton density weighted image of the object, generate a B1+ field map of the object, generate a transmit-corrected image based on the B1+ field map and based on the proton density weighted image, electronically filter the transmit-corrected image to generate a receive sensitivity map, and revise the original image using the receive sensitivity map.
