The method comprises the step: accommodating a turbid medium (1) to which a fluorescent contrast agent has been administered in a measurement volume (4). The fluorescent contrast agent is capable of emitting light in a first range of wavelengths upon irradiation with light. The method further comprises: performing attenuation measurements at a plurality of different wavelengths (λi, . . . , λk) by subsequently irradiating the turbid medium (1) with light from a plurality of different source positions and detecting light emanating from the turbid medium (1) in a plurality of detection positions for each source position; reconstructing absorption properties (μa(r, λ) as a function of the position in the interior of the turbid medium (1) 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 (1) for wavelengths of the first range of wavelengths; performing a fluorescence measurement by subsequently irradiating the turbid medium (1) 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; and reconstructing a fluorescence image of the spatial distribution of the fluorescent contrast agent in the interior of the turbid medium (1) from the fluorescence measurement using the calculated absorption properties."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for reconstructing a fluorescent image of the interior of a turbid medium and device for imaging the interior of a turbid medium","description":"A method for reconstructing a fluorescence image of the interior of a turbid medium is provided.
