摘要：
A method of imaging is presented. The method includes reconstructing image data acquired at a plurality of time intervals to obtain a plurality of images. Further, the method includes generating a mean image using the plurality of images. The method also includes correcting motion in the mean image or the plurality of images or both the mean image and the plurality of images by iteratively determining convergence of the mean image or the plurality of images or both the mean image and the plurality of images to generate a converged mean image, a converged plurality of images, or both a converged mean image and a converged plurality of images.
