OPTISCHE CT-VORRICHTUNG UND VERFAHREN ZUR WIEDERHERSTELLUNG VON BILDERN |
摘要 |
An optical CT apparatus 10 is mainly composed of a container 12 filled with an optical interface member 20; a light-projecting section, comprising a light source 22 and an optical switch 24, for projecting light into the container 12; a light-detecting section, comprising photodetectors 30 and shutters 32, for detecting the light from the inside of the container 12; and an arithmetic/control section 14 for calculating a spatial distribution of absorption coefficient. The arithmetic/control section 14 has a function of determining a spatial distribution of a characteristic amount concerning a part of an object to be measured 200 according to a comparison of an optical intensity signal actually measured by each detector 30 in a state where the container 12 is filled with the optical interface member 20 with an optical signal actually measured by each detector 30 in a state where the optical interface member 20 is partly replaced by the part of object to be measured 200. <IMAGE> |
