Figure 2.
Comparison of APT-weighted images on a motion-corrupted data set from a normal volunteer without and with registration using different reference images. APTw images from original non-registered data (a) and registered data with the 3.5 ppm dynamic image (b), the mean of all dynamics (c), and the S0 dynamic (d) as the reference images. A proper registration reference is required to improve the quality of motion-corrupted data. The corresponding uniformity indices are shown on the left side and the color bar is shown at the bottom.
