Within tissue engineering the restore, replacement or regeneration of defective tissues and their function by biological substitutes is monitored. To monitor this process contrast agents that contain fluorine atoms are used. Defects that are inflicted on a rat hind leg are imaged on 1H and 19F. An overlay of these image provides a good insight in the healing process. We present a Helmholtz pair that has a good coverage and good SNR to image rat hind leg. The Helmholtz pair is combined using a Wilkinson lumped element divider/ splitter.
