Fig. 5

Reconstruction comparison of a subject with 6 times accelerated Poisson disc undersampling. Reconstruction results are shown at 30th and 68th frame. Each column corresponds to direct SPIRiT reconstruction with registration (a, f), non-motion corrected k-t PCA (b, g) and k-t SLR (c, h), motion corrected k-t PCA (d, i) and k-t SLR (e, j). The temporal x and y-shifts of the heart position derived from rigid registration of the SPIRIT images (k) demonstrate that the patient took a deep breath near frame 60. The x-t profiles for the above 5 reconstruction methods are shown (l-p) with colored arrows denoting the 30th and 68th frames
