Spatial Resolution Enhancement through Time Gated Measurements
Near infrared optical transillumination of tissue is emerging as a new tool in clinical diagnosis. Its advantages are noninvasiveness and portability and its wealth of light-tissue interaction mechanisms yielding information on physiological functions. The main chromophores in tissue in the wavelength range from 600 nm to 1000 nm are beside fat and water the oxygenated and deoxygenated form of hemoglobin, myoglobin and cytochrom, all of which are essential for the oxygen metabolism of living cells.
