Figure 7. Correction of nonlinear motion artifacts in three-dimensional image volumes. (A) Single image from a three-dimensional image volume collected from the kidney of a living rat after intravenous injection of 110 000 MW fluorescein dextran. (B) XZ sections of volumes reconstructed from original data (top), following rigid registration (middle) and following non-rigid registration (bottom). Field is 197 microns across.
