1. An imaging method, comprising: reconstructing gated emission tomography images for a local region of interest; comparing the gated emission tomography images to a computed tomography image of the local region of interest to determine if there is a mismatch between the gated emission tomography images and the computed tomography image; adjusting the mismatch between the gated emission tomography images and the computed tomography image of the local region of interest common to the computed tomography image and the emission tomography images; registering the gated emission tomography images; and combining the registered gated emission tomography images to generate motion corrected images.
