    摘要: Light irradiates one light incident position on the surface of a scattering-absorption body. The light that propagates through the interior of the scattering-absorption body is detected at one light detecting position on the surface of the scattering-absorption body. On the basis of a light detection signal, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of the light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region to be measured are calculated. The information relating to the amount of substance to be measured is corrected on the basis of the mean optical path length, such that the longer the mean optical path length, the greater the amount of substance to be measured is.

    摘要: The bioinstrumentation apparatus includes a light irradiation unit irradiating a measurement region with light, a light detection unit detecting diffused light from the measurement region, and a computing unit generating a reconstructed image for the interior of the measurement region. The computing unit calculates J coefficients wj set for every pixel of the reconstructed image and more than 0 and not more than 1 (where J is the number of pixels of the reconstructed image) and carries out successive approximation computation by the following iterative formula xj(k+1)=xj(k)+wjdj(k) (where k is an integer from 1 to N, N is the number of times of iterative computation, xj(k) is a pixel value of the jth pixel on the kth iterative computation, and dj(k) is an update amount of the jth pixel on the kth iterative computation) to generate the reconstructed image.

    摘要: The position of a metal marker 5 relative to an optical fiber 6 is fixed, and the metal marker 5 can be moved up close to a target site such as a thrombus. It is preferable that the position, in an optical fiber longitudinal direction, of a front-end face of the optical fiber 6 is coincident with the position, in an optical fiber longitudinal direction, of a front-end face of the metal marker 5. More specifically, since the distance between the target site and the front end of the optical fiber 6 is known by radiography, it becomes unnecessary to use a large quantity of contrast agent and irradiate a laser beam depending on skill and intuition, and therefore an effective laser beam irradiation becomes possible.

    摘要: A scattering medium measuring apparatus is composed of: a measuring module 1 having an irradiation probe 11 and detection probes 61 and 71; and a measuring module 2 having an irradiation probe 21 and detection probes 81 and 91. There is also provided an optical delay device 22 between a pulse light source 30 as a common light source for the irradiation probes 11 and 21 and the irradiation probe 21 so that pulse light is irradiated successively from the irradiation probes 11 and 21. A trigger circuit 50 is adapted to instruct the light source 30 on the irradiation timing of pulse light and signal processing circuits 62 to 92 corresponding to the detection timing of the corresponding light synchronized with the irradiation timing. This can achieve a scattering medium measuring apparatus and measuring method capable of suppressing crosstalk between channels without a spatial restriction.
