Abstract: A mammography device is disclosed. The mammography device includes a container configured to surround the breast and a plurality of optical fibers attached to be directed inward in the container and configured to perform radiation and detection of light. The container has a base member having an opening, a plurality of annular members continuously disposed to come in communication with the opening, and a bottom member disposed inside the annular member spaced the farthest distance from the base member. The annular members and the bottom member are configured to relatively displace the adjacent annular member on the side of the base member or the base member in a communication direction. Some of the plurality of optical fibers is attached to the plurality of annular members.

Abstract: A scattering absorber measurement device includes a light source for outputting a plurality of light pulses having different wavelengths input to a scattering absorber, a photodetector for detecting each light pulse propagating inside the scattering absorber and output a detection signal, and a computation unit for calculating a reduced scattering coefficient and an absorption coefficient according to a time-resolved spectroscopic measurement method on the basis of the detection signal. The computation unit determines data related to a ratio of reduced scattering coefficients among wavelengths of the plurality of light pulses and calculates the reduced scattering coefficient and the absorption coefficient on the basis of a time-resolved measurement profile of each wavelength based on the detection signal and the data related to the ratio.
