摘要： An optical coherence tomography device includes an OCT optical system that irradiates a tissue of the subject's eye with measurement light from a light source, and detects interference between reference light and the measurement light reflected from the tissue by using a detector, and a processor, in which the processor performs a generation process of acquiring A-scan data based on a signal output from the detector in a cycle of 300 kilohertz or more and generating three-dimensional OCT data at any time based on the acquired A-scan data, and performs an analysis process on each piece of the three-dimensional OCT data generated at any time through the generation process, so as to output a real-time analysis result of the three-dimensional OCT data which is generated at any time.

摘要： The present disclosure relates to an optical coherence tomography (OCT) including: an OCT device, an OCT calculation method, and an OCT calculation program, enabling correlation between images to be easily performed; more specifically it relates to a case where a functional OCT image such as a motion contrast is acquired by using the OCT; acquiring the functional OCT image through a calculation process of an OCT signal is a time-consuming process, for this reason, a long time elapses until the point that a functional OCT image can be observed after OCT imaging is completed, and thus this causes stress to a subject and an examiner; the present disclosure provides an OCT device, an OCT calculation method, and an OCT calculation program, enabling a functional OCT image to be rapidly acquired and enables an examiner to easily perform diagnosis.
