Patent ID: 6957096

Claim:
A method of reconstructing an image of a region of interest inside a scattering medium, the method utilizing a map of distribution of the intensity of electromagnetic radiation components scattered from tagged locations within said region of interest, said map corresponding to certain relative positions of at least one source of the electromagnetic radiation ( 14 ) and at least one detector ( 16 ) of the scattered electromagnetic radiation with respect to one another and with respect to the tagged locations inside the medium the method being characterized in that: data indicative of said relative positions of the at least one electromagnetic radiation source and that at least one scattered radiation detector is utilized to provide a mathematical model that presents a relation between a map of distribution of the intensity of electromagnetic radiation components γ scattered from tagged locations in a medium and a halftone map of an attenuation factor μ(r), which is a function of spatial variations of scattering and absorption coefficients of the mediums said relation being indicative of a degree of inhomogeneity of at least one of the scattering and absorption coefficients within the medium; and, said mathematical model is utilized for processing the map of the distribution of the electromagnetic radiation components to thereby obtain a halftone pattern of said region of interest.
