PROBLEM TO BE SOLVED: To provide an OCT apparatus and an OCT control program which efficiently correct the misalignment of an image caused by a movement of a subject eye.SOLUTION: There is provided an OCT apparatus which captures a tomographic image of a subject using optical interference between measurement light and reference light, the OCT apparatus comprising: scan means for scanning the subject with the measurement light and control means for controlling the scan means such that each time a scan cycle to scan the measurement light along a scan path is repeated a plurality of times at the same position, the position of the scan path is changed within an imaging range, with the scan path before and after the change overlapping each other in at least one point.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】被検眼の動きによる画像のずれを効率よく補正するOCT装置、およびOCT制御プログラムを提供する。【解決手段】測定光と参照光との光干渉を利用して被検体の断層画像を得るOCT装置であって、前記被検体に対して前記測定光を走査させる走査手段と、前記走査手段を制御し、走査経路に沿って前記測定光を走査させる走査サイクルを同じ位置で複数回繰り返させるたびに、撮影範囲内で前記走査経路の位置を変更する制御手段と、を備え、前記制御手段は、変更前後の前記走査経路が少なくとも1点で重なるように前記走査経路の位置を変更することを特徴とする。【選択図】図3
