Validation using metrics of errors in the slope and the overall time curve. Initially, each reference data set was registered to estimate the deformation maps that correspond to the breathing motion. These maps were used to deform the reconstructions followed by which two error metrics were evaluated. With respect to the reference images, the error in the slope and error in the l2 norm of the pixel time series were calculated for the different reconstructions as depicted in (A). This was done for all the pixels belonging to regions of the myocardium for all the data sets. The mean +/- standard deviation of these metrics are plotted in (B) and (C). We observed consistently reduced errors with k-t SLR in comparison to STCR and k-t SPARSE/SENSE.
