Abstract
The internal physiological compositional state of an individual examination subject for example a human breast is assessed by transmission of selected light energy spectra into the interior of such subject, detecting the selected spectra after transversal of a distance within the object, quantifying the detected light energy at selected wavelengths, conditioning the obtained value sequence on the basis of distance, determining at least one composite averaged value from the conditioned value, and using such as a characterizing value in comparison with analogously obtained values representative for example of a norm in order to asses the internal state of the subject.
