Paper Abstract

Human forearm oxygenation and scattering changes during ischemia were investigated using picosecond near infrared laser spectroscopy. Path lengths were calculated for different geometries. At 760 nm, a plateau phaser was reached after 4 min occlusion. No changes were observed during the occlusion at 800 nm, the hemoglobin isosbetic wavelength. Time-resolved Monte Carlo simulations were performed also to mimic the propagation of a light pulse in a forearm phantom containing different quantity and size of polystyrene spheres as scattering media. The influence of both the scattering and absorption effects was studied.
