beginning of the study an axial 3d spoiled gradient echo sequence spgr u03b1 30 u00b0 fov 24 cm 192 u00d7 192 u00d7 56 tr te 33 8 6 8 msec 1 4 mm slice thickness with magnetization transfer mt based tissue suppression u03b1 930 u00b0 0 25 duty cycle and a positive ramped rf excitation tone pulse with support for aforementioned adaptive motion correction was implemented on a 1 5 t ge signa excite unit ge healthcare a healthy volunteer male 28 y underwent three consecutive scans each consisting of a single 7 7 cm 3d slab that covers the circle of willis whereby for each acquisition instructions were given to perform a specific motion pattern fig1 a to remain still fig1 b c to perform head motion as much as permitted by the coil instructions to change position were given via intercom to assure reproducibility between both experiments motion was tracked for all 3 experiments to assure that the motion of the two motion experiments were of comparable extent fig1 a c shows the tof maximum intensity projections mip that correspond to the 3 experiments clearly the cut out mips were best on the u2018 no motion u2019 case fig1 a whilst the u2018 uncorrected motion.
