Abstract (en)
[origin: WO9904683A1] The invention relates to a method for evaluating the distribution of scattered light resulting from the local transillumination of a living organism, by determining characteristic values. A region of the living organism in a predetermined transillumination site is transilluminated with light of a wavelength preferably in the range of an optical tissue window, in order to record the distribution of scattered light. The distribution of scattered light is recorded in the form of a spread function. One or several characteristic values which characterise the spread function are determined by calculation, based on the form of the spread function, and used as a basis for the evaluation. An approximation function parametrising the spread function is produced in order to determine the characteristic values for said spread function, the parameters of said approximation function representing said characteristic value or values. Section parameters in the form of site-specific section lengths of characteristic areas of the spread function are also determined as optional further characteristic values.
