Summary:PROBLEM TO BE SOLVED: To provide an optical coherence tomography device capable of solving at least one of conventional technologies, and a fundus image processing program.SOLUTION: The optical coherence tomography device includes an OCT optical system for detecting an A scan signal due to interference by measurement light scanned on a subject by scanning means and reference light corresponding to the measurement light, and image processing means for acquiring three-dimensional OCT data in which the A scan signal at each scanning position is arrayed in a two-dimensional manner, and processing the acquired three-dimensional OCT data to generate an OCT front image. In the optical coherence tomography device, the image processing means acquires a histogram of the A scan signal at each scanning position, and forms an OCT front image on the basis of the acquired histogram.SELECTED DRAWING: Figure 4 【課題】 従来技術の少なくとも一つを解決可能な光コヒーレンストモグラフィー装置、および眼底画像処理プログラムを提供する。【解決手段】 被検体上を走査手段によって走査された測定光と、前記測定光に対応する参照光との干渉によるＡスキャン信号を検出するためのＯＣＴ光学系と、各走査位置でのＡスキャン信号が二次元的に配列された３次元ＯＣＴデータを取得し、取得された３次元ＯＣＴデータを処理してＯＣＴ正面画像を生成するための画像処理手段と、を備える光コヒーレンストモグラフィー装置であって、前記画像処理手段は、各走査位置での前記Ａスキャン信号のヒストグラムを取得し、取得された前記ヒストグラムに基づいて、ＯＣＴ正面画像を形成させることを特徴とする。【選択図】 図４
