Abstract: An OCT apparatus of an exemplary aspect includes an OCT scanner, image data generating unit, registration unit, and image data composing unit. The OCT scanner is configured to acquire three dimensional data sets by applying an OCT scan to mutually different three dimensional regions of a sample. The image data generating unit is configured to generate a plurality of pieces of image data from the three dimensional data sets. The registration unit is configured to perform a first registration between the plurality of pieces of image data by applying an image correlation calculation to each of overlap regions in the plurality of pieces of image data. The image data composing unit is configured to compose the plurality of pieces of image data based on a result of the first registration.

Abstract: A storage device of an ophthalmologic image display device of an embodiment stores a three dimensional data set acquired by scanning a subject's eye using OCT. An image processor forms, based on the three dimensional data set, a B-mode image, front images, and composite front image obtained from the front images. A display controller displays the B-mode image, front images and composite front image in a predetermined layout. The display controller displays distinguishment color information for distinguishment between the front images by colors and slice area information that indicates a partial region of the B-mode image corresponding to a slice area of the three dimensional data set represented by each front image in a color according to the distinguishment color information, and displays a composite front image based on the front images, each of which is expressed by a color according to the distinguishment color information.

Abstract: An exemplary aspect is a method of processing data acquired by applying an optical coherence tomography (OCT) scan to a sample. The method includes preparing a three dimensional data set acquired from a sample, creating a two dimensional map based on representative intensity values of a plurality of pieces of A-scan data included in the three dimensional data set, placing the three dimensional data set based on the two dimensional map, and executing a process based on at least a partial data set of the three dimensional data set on which placement based on the two dimensional map has been performed.
