Normalized Transillumination of Fluorescent Proteins in Small Animals

Molecular Imaging, 2006
We investigated the capacity of normalized transillumination methods in imaging fluorescent proteins in visible light, in phantoms and in live mice. We demonstrate significant imaging improvements over epi-illumination imaging, as commonly applied today.
