ABSTRACT:
A method for detecting a complete or partial obstruction in a vessel through an intervening fluid includes receiving spectroscopic responses at different locations of a vessel wall, e.g., a vein or artery, through an intervening fluid, preferably blood. Spectroscopic responses are generated by irradiating the vessel wall at different locations and detecting spectra at those locations. In preferred embodiments, the radiation used is in the near infrared (NIR) region of the electromagnetic spectrum. The thrombus is located by determining whether fluctuations, spatial and/or spectral, of the spectral responses are indicative of thrombus.
