Patent ID: 8520921

Claim:
A method for reconstructing a fluorescence image of the interior of a turbid medium, the method comprising: accommodating a turbid medium to which a fluorescent contrast agent has been administered in a measurement volume, the fluorescent contrast agent being capable of emitting light in a first range of wavelengths upon irradiation with light; performing attenuation measurements at a plurality of different wavelengths by subsequently irradiating the turbid medium with light from a plurality of different source positions and detecting light emanating from the turbid medium in a plurality of detection positions for each source position, wherein the plurality of different wavelengths are in a second range of wavelengths that differs from the first range of wavelengths; reconstructing absorption properties as a function of the position in the interior of the turbid medium for the plurality of different wavelengths from the attenuation measurements; calculating absorption properties as a function of the position in the interior of the turbid medium for the wavelengths of the first range of wavelengths; performing a fluorescence measurement by subsequently irradiating the turbid medium with light causing the fluorescent contrast agent to emit light in the first range of wavelengths from the plurality of source positions and detecting the light emanating from the fluorescent contrast agent in the plurality of detection positions for each source position; reconstructing a fluorescence image of the spatial distribution of the fluorescent contrast agent in the interior of the turbid medium from the fluorescence measurement using the calculated absorption properties.
