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: An apparatus for magnetic resonance imaging includes processing circuitry to obtain a set of sequence instructions for performing a magnetic resonance scan; partition the obtained set of sequence instructions into a plurality of kernels by determining partition time points defining boundaries of the plurality of kernels, wherein the partition time points are not equally spaced in time; convert a first kernel of the plurality of kernels into a first hardware instruction set; transmit the first hardware instruction set to a hardware board controller for execution; and reconstruct a magnetic resonance image from received data, including data obtained by executing the first kernel.
