Respiratory motion remains a major challenge to the use
of MRI in the body and techniques that restrict
intra-scan motion utilizing breath-holding or gating are
prone to error. In this work, we investigate use of aT1
weighted sliding slice approach that casts intra-scan
motion as geometric distortion rather than aliasing. In
phantoms and initial volunteer images, we demonstrate
improved image quality compared to traditional 3D golden
angle radial sampling and a profound robustness to
motion.
