Abstract:
A method of performing tissue spectroscopy in a mammalian body, the method comprising:(a) providing a housing comprising a distal portion and a proximal portion, the distal portion enclosing a spectrometer comprising a light source, a bichromatic filter, and a plurality of sensors, the housing enclosing electronics, the electronics being electrically connected to the plurality of sensors; (b) inserting the distal portion into the mammalian body; (c) emitting light from the light source, passing the light through the bichromatic filter to cause a tissue to fluoresce; (d) detecting tissue fluorescence through at least one of the plurality of sensors; (e) generating electric signals in response to tissue fluorescence detected by the sensors; (f) transmitting the electric signals to the electronics for processing the signals and generating information regarding the tissue.
