    • A measurement data correction method is provided. 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 includes: 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 an obtained first measurement data and an obtained first standardization measurement data using a defined correction coefficient.
    • 提供测量数据校正方法。 使用生物体作为测试样品,由施用于测试样品的荧光物质的激发光产生的荧光被测试样品周围的多个位置处的光接收部件在通过的平面内被接收 测试样本的观察部位,并且该方法用于沿着穿过观察部位的平面重建测试样品的光学断层图像。 该方法包括:根据获得的第一测量数据和所获得的第一标准化测量数据,生成校正的测量数据,作为用于沿着穿过测试样本的观察部位的平面的光学断层图像重建中使用的测量数据,使用 定义的校正系数。
