Patent ID: 8410456

Claim:
A measurement data correction method, wherein, a living organism is employed as a test sample, fluorescent light generated by excitation light from a fluorescent substance administered to the test sample is received by a light receiving component at a plurality of locations around the periphery of the test sample in a flat plane passing through an observation site of the test sample, and the method is employed for reconstruction of an optical tomographic image of the test sample along the flat plane passing through the observation site, the method comprising: acquiring first measurement data that is measurement data in a flat plane passing through the observation site and acquiring second measurement data that is measurement data in a flat plane passing through a site of interest of the test sample different from the observation site; using a predetermined standardization sample for the test sample to acquire first standardization measurement data that is measurement data in a flat plane corresponding to the flat plane of the observation site, and to acquire second standardization measurement data that is measurement data corresponding to a flat plane of the site of interest; using the second measurement data and the second standardization measurement data corresponding to the site of interest of the test sample, and setting a correction coefficient such that the second standardization measurement data is cancelled out by the second measurement data; and generating corrected measurement data, as measurement data to be used in reconstruction of an optical tomographic image along the flat plane passing through the observation site of the test sample, from the first measurement data and the first standardization measurement data using the correction coefficient.
