Ratio of centerline AUC to blood sampled AUC averaged over all subjects (n = 14) for left and right carotids. Single polynomial of 9th order and 5 control point spline centerline models were used. “Initial” values are derived from centerline positioning using the original brain registration. “Registered” values are derived from centerline positioning using the local re-registration. Far right “avg” values are averaged over left and right carotids.
