The In-Vivo Xtreme Imaging System (Bruker BioSpin Corp., Billerica, MA) is an optical
and X-ray small animal imaging system that can noninvasively view and measure the
levels of optically tagged molecules in a live animal.
Typically, the molecules to be viewed (e.g. proteins) are tagged by fluorescence or bioluminescence. The imaging system allows delivery of gas anesthesia to animals prior to imaging.
