Abstract: A method of generating an image in one embodiment includes acquiring, with a computed tomography (CT) acquisition unit, CT projection data from at least a region of interest (ROI), and concurrently acquiring, with a magnetic resonance (MR) acquisition unit, MR imaging information of at least a portion of the ROI. The method also includes determining a motion of the at least a portion of the ROI using the MR imaging information, and reconstructing the image using the CT projection data. Reconstructing the image includes motion correcting the CT projection data based on the motion determined using the MR imaging information.
