Abstract
A system for performing near infrared spectroscopy (NIRS) monitors tissue oxygenation and/or hemodynamics. The system comprises a sensor coupled to a controller and/or processing device. The sensor comprises a light source which is operable to emit light of various distinct wavelengths and a detector which is operable to collect corresponding backscattered light.
Claims20
A near infrared spectroscopy (NIRS) sensor comprising:
- a body having a dorsal face, a ventral face, and proximal and distal ends, the body supporting a light source and a photodetector in a spaced apart relationship, the light source operative to emit light from the ventral face of the body and the photodetector operative to detect light incident on the ventral face of the body and to generate an output signal;
- a flexible flap extending laterally from the body along opposed first and second sides of the body.
A method for monitoring one or more characteristics of tissue by near infrared spectroscopy (NIRS) the method comprising:
- controlling a light source to sequentially illuminate the tissue with light of a plurality of different wavelengths and, for each of the wavelengths detecting a portion of the light that is backscattered from the tissue at a photodetector;
- processing an output signal of the photodetector to yield a measure of one or more NIRS parameters.
