We present a method for retrospective motion-correction of silent ZTE for quantitative T1 and T2 mapping using self-navigation. A spiral phyllotaxis k-space trajectory was used to reconstruct motion navigators, which then were co-registered to obtain motion parameters. The method is demonstrated for neuroimaging, showing improved image quality of quantitative T1 and T2 maps after motion correction. These results further showcase the capacity of ZTE for robust, silent neuroimaging.
