Abstract: A method for determining an intensity-corrected magnetic resonance image includes acquiring B1 projection data of a patient using a magnetic resonance imaging system. The method also includes determining a transmit map using only the acquired B1 projection data. The method further includes acquiring an image of a patient using magnetic resonance imaging system and correcting an image intensity of the acquired image using the determined set of maps. The method also includes outputting the corrected image of the patient.

Abstract: A patient couch for use in a medical imaging system that includes a gantry, a power supply unit and a driving unit for positioning the patient couch with respect to the gantry. The patient couch includes at least a first connector for supplying a wireless coil (e.g., a radio frequency (RF) coil for an MRI imaging apparatus) with power. The patient couch is detachably connected to the gantry. The power supply is configured to supply the first connector with power and an optional clock synchronization signal.
