MULTI-DIMENSIONAL ITERATIVE PHASE-CYCLED RECONSTRUCTION FOR MRI IMAGES
摘要
Methods, systems, computer programs, circuits and workstations are configured to carry out image processing to generate MRI images with reduced aliasing artifacts (e.g., Nyquist and/or motion-induced image artifacts) by (a) electronically reconstructing a series of images using patient image data obtained from a patient MRI image data set by iteratively cycling through different estimated values of phase gradients in at least two dimensions; and (b) electronically selecting an image from the reconstructed images as having a lowest artifact level.
