Method for three-dimensional, inhomogeneity localization in turbid medium using diffuse photon density waves

摘要

Three dimensional localization of a cancer tumor is performed by amplitude-modulated optical radiation producing a time varying photon distribution in the body of the patient examined. The amplitude and phase of the diffuse photon density wave (DPDW) are measured in the detection plane and a novel algorithm is employed enabling three-dimensional tumor localization to occur with only one measurement and without the need for a moving radiation scanner.
