PROBLEM TO BE SOLVED: To provide the distribution of a fluorescence emission amount inside a body to be measured and to generate fluorescent tomographic images based on the distribution of the fluorescence emission amount. SOLUTION: The breast 4 of a subject to which a fluorescent reagent is administered beforehand is irradiated with first extremely-short pulse light L2, the spatial distribution and time change of the light quantity of extremely-short pulse light L4 propagated inside the breast 4 are detected by a photodetection part 32, and the distribution of an optical characteristic value inside the breast 4 is calculated on the basis of the detected result of the photodetection part 32 by an optical characteristic value distribution calculation part 47. Also, second extremely-short pulse light L3 is emitted to the breast 4, the spatial distribution and time change of the light quantity of fluorescence L4 originated from the inside of the breast 4 and propagated inside the breast 4 by irradiation with the second extremely-short pulse light L3 are detected by the photodetection part 32, and the distribution of the fluorescence emission amount inside the breast 4 is calculated on the basis of the detected result and the optical characteristic value distribution in a fluorescence distribution calculation part 48. On the basis of the distribution of the fluorescence emission amount, the fluorescent tomographic image of the breast 4 is generated and displayed. COPYRIGHT: (C)2006,JPO&NCIPI
