Measurement data correction method, optical tomography measurement device and storage medium stored with program

An optical tomography measurement device, wherein,

• a living organism is employed as a test sample, fluorescent light is generated by excitation light from a fluorescent substance administered to the test sample, and the device performs reconstruction, from measurement data obtained from receiving light with 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, of an optical tomographic image of the test sample along the flat plane passing through the observation site, the device comprising:
• a first acquiring component that acquires with the light receiving component first measurement data that is measurement data in a flat plane passing through the observation site and 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;
• a second acquiring component that uses a predetermined standardization sample for the test sample to acquire with the light receiving component first standardization measurement data that is measurement data in a flat plane corresponding to the flat plane including the observation site, and to acquire second standardization measurement data that is measurement data corresponding to a flat plane including the site of interest;
• a correction coefficient setting component that uses the second measurement data and the second standardization measurement data corresponding to the site of interest of the test sample, and sets a correction coefficient such that the second standardization measurement data is cancelled out by the second measurement data;
• and
• a correction component that generates corrected measurement data, of 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.

A non-transitory storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to function the computer, for a living organism employed as a test sample, fluorescent light generated by excitation light from a fluorescent substance administered to the test sample being 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, functioning the computer as components for performing reconstruction of an optical tomographic image of the test sample along the flat plane passing through the observation site from measurement data obtained by the light receiving component, the components comprising:

• a first acquiring component that acquires with the light receiving component first measurement data that is measurement data in a flat plane passing through the observation site and 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;
• a second acquiring component that uses a predetermined standardization sample for the test sample to acquire with the light receiving component first standardization measurement data that is measurement data in a flat plane corresponding to the flat plane including the observation site, and second standardization measurement data that is measurement data corresponding to a flat plane including the site of interest;
• a correction coefficient setting component that uses the second measurement data and the second standardization measurement data corresponding to the site of interest of the test sample, and sets a correction coefficient such that the second standardization measurement data is cancelled out by the second measurement data;
• and
• a correction component that generates corrected measurement data, of 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.
