Abstract:
Time-resolved optical tomography systems using a short pulse laser, may be used in detection and treatment of cancer and tumors. Information is conveyed about tissue interior by the temporal variation of the observed scattered, and reflected measured when short-pulse lasers interact with scattering-absorbing media like tissue. Multiple scattering-induced temporal signature that persists for time periods greater than the duration of the source pulse and is a function of the source pulse width, the scattering and absorbing properties of the medium, and the location in the medium where the properties undergo changes. If the detection is carried out on the same short time scale (comparable to the order of the pulse width), the signal continues to be observed even for long durations after the pulse has been off due to the time taken for the photons to migrate to the detector after multiple scattering in the tissue media.
