1. A method of imaging using optical coherence tomography (OCT), the method comprising:
designating an imaging region in a sample with reference to information on a past imaging region designated in a past examination of the sample;
setting a plurality of target regions to include the imaging region with reference to information on past target regions designated in the past examination of the sample;
acquiring a plurality of three dimensional data sets from a plurality of three dimensional regions of a sample different from each other by sequentially applying an OCT scan to the plurality of target regions;
generating a plurality of pieces of image data from the plurality of three dimensional data sets;
performing a first registration between the plurality of pieces of image data by applying an image correlation calculation to each of a plurality of overlap regions in the plurality of pieces of image data;
composing the plurality of pieces of image data based on a result of the first registration; and
extracting a partial image data group corresponding to the imaging region from the plurality of pieces of image data based on the result of the first registration, and composing the partial image data group.
