Optical tomographic image photographing apparatus

摘要

An optical tomographic image photographing apparatus includes: an OCT optical system for capturing tomographic images of an object to be examined, the OCT optical system including a light source, a splitter for splitting a light from the light source into a measurement optical path and a reference optical path, an optical scanner, and a detector for detecting a spectrum of light obtained by combining the light of the measurement optical path reflected from the object and the light from the reference optical path; a drive unit to move at least a part of optical components of the OCT optical system in an optical axial direction; a monitor to output at least the tomographic image; and a display controller for displaying the tomographic image and identifying information used to determine whether the tomographic image output to the monitor is a normal image or a reverse image.

1. An optical tomographic image photographing apparatus, including:
an optical coherence tomography (OCT) optical system that captures tomographic images of an object to be examined, the OCT optical system including:
a light source;a splitter that splits a light from the light source into a measurement optical path and a reference optical path;an optical scanner, placed in the measurement optical path, that scans light on the object to be examined; anda detector that detects a spectrum of light obtained by combining the light of the measurement optical path reflected from the object and the light from the reference optical path; a drive unit configured to move at least a part of optical components provided in the OCT optical system in an optical axial direction to adjust a difference in optical path length between the measurement optical path and the reference optical path; a monitor configured to output at least the tomographic image; and a display controller that includes a processor and that is configured to determine, based on an output from the detector, identifying information identifying whether the tomographic image output to the monitor is a normal image or a reverse image, and to display the identifying information on the monitor alongside the tomographic image.
