Abstract:
1. A method of localizing a deviant region in a turbid medium that is represented by a set of volume elements, which method includes first irradiating the turbid medium with light comprising radiation of mainly a first wavelength: first measuring intensity of the light comprising radiation of mainly the first wavelength as it is transported along a plurality of light paths through the turbid medium; and second irradiating the turbid medium with light comprising radiation of a second wavelength which is not equal to the first wavelength; second measuring intensity of the light comprising radiation of mainly the second wavelength as it is transported along a plurality of light paths through the turbid medium; reconstructing an image ( displaying the reconstructed image, further including: calculating: displaying a point in the image that corresponds to one of the volume elements, and measuring the turbid medium after it is irradiated by means of light comprising radiation of mainly a third wavelength not equal to the first and second wavelengths as it is transported along a plurality of light paths through the turbid medium, calculating an intensity value for the volume element and a significance value is assigned to the volume element in dependence on the value of the first parameter and on a value of a second parameter.
