title: Scanning fluorometer for the rapid assessment of pyridine nucleotide and flavoprotein fluorescence changes in tissues in vivo.
abstract: This paper describes a scanning fluorometer which produces images in real time of the distribution of pyridine nucleotide or flavoprotein fluorescence at the surface of tissues in vivo. The basic difference between this device and others reported in the literature is that fluorescence changes at any selected point within the image can be quantified as they occur. We suggest that the apparatus has potential application in those areas of surgery where vascular replacement or repair is required and where it would be advantageous to have an immediate measure of the cellular response to a return of blood flow.
