Abstract: PROBLEM TO BE SOLVED: To acquire information on the interior of a scatter absorber more accurately and simply in consideration of a device function even in cases where noises are included in measured waveforms.
SOLUTION: In this method of measuring a scatter absorber, pulsed light of a prescribed wavelength is caused to enter a scatter absorber which is a measuring object and a scatter absorber for reference (S01b and S02b). The pulsed light having propagated through the interior of the scatter absorber is detected to acquire light detection signals (S01c and S02c). Measured waveforms are acquired based on the detected signals (S01d and S02d). The parameters of a function indicating a theoretical waveform of the measuring object are determined so that the result of a convolution computation of the theoretical waveform of the measuring object and the measured waveform for reference equals to the result of a convolution computation of a theoretical waveform for reference and the measured waveform of the measuring object (S03). Information on the interior of the scatter absorber is calculated based on the theoretical waveforms indicated by the function (S04).

Abstract: PROBLEM TO BE SOLVED: To provide a catheter which can effectively irradiate an object with a laser beam and an examination system which can effectively dissolve a thrombus as the object. SOLUTION: The location relation of a metal marker 5 and an optical fiber 6 is fixed and the metal marker 5 can be moved to the nearness of a target place such as the thrombus. In addition, a longitudinal position of the optical fiber at the end surface of the optical fiber 6 is in agreement with the longitudinal position of the optical fiber at the end surface of the metal marker 5. That is, since the distance between the target place and the leading edge of the optical fiber 6 becomes clear by roentgenography, it is unnecessary to employ a large quantity of a contrast medium and to irradiate it with the laser beam depending on a skill or intuition and therefore the effective irradiation with the laser beam is possible.
