Patent ID: 7046832

Claim:
A computer-implemented method for imaging of the properties of at least one scattering target medium, comprising: generating a first vector of measured data and a second vector of measured data, the first vector being indicative of energy emerging from the at least one scattering target medium, the second vector being indicative of energy emerging from the at least one scattering target medium, the emerging energy substantially originating from at least one source directing the energy into the at least one scattering target medium; normalizing a difference between the first and second vectors according to a ratio of: (a) a difference between the first and second vectors, to (b) the second vector; solving a modified perturbation equation of a radiation transport inverse problem for a relative change between a known property of a reference medium and a corresponding unknown property of the at least one scattering target medium, wherein the modified perturbation equation relates the normalized difference and a vector of reference data for the known reference medium to the relative change in the property, the vector of reference data being indicative of energy emerging from the known reference medium; and generating an image of the at least one scattering target medium, responsive to the solving.
