    • An information processing apparatus for frequency domain optical coherence tomography comprises an image scanning unit that receives measurement data from an optical coherence tomography device, while moving a measurement point to the next adjacent point at each measurement time by controlling the optical coherence tomography device, and generates depth information based on the measurement data to produce a raw tomographic image. The apparatus includes a noise reduction unit that reduces noise from the raw tomographic image to produce a result tomographic image. The noise reduction unit reduces the noise from the raw tomographic image by subtracting the depth information generated by the image scanning unit at each measurement time from the depth information generated at another measurement time adjacent to said each measurement time.
    • 用于频域光学相干断层摄影的信息处理装置包括:图像扫描单元,其通过控制光学相干断层摄影装置在每个测量时间将测量点移动到下一相邻点,从光学相干断层摄影装置接收测量数据,并产生 基于测量数据的深度信息以产生原始断层图像。 该装置包括降噪单元,其降低来自原始断层图像的噪声,以产生结果断层图像。 噪声降低单元通过从与每个测量时间相邻的另一测量时间产生的深度信息减去在每个测量时间由图像扫描单元生成的深度信息来减少来自原始断层图像的噪声。
