Fundus observation apparatus

摘要

Distribution information of examination results of eye fundus is displayed. An imaging part carries out movie imaging of fundus. A tomographic image forming part comprises an optical system that generates and detects interference light by superposing signal light from fundus on reference light and a scanner that scans fundus with signal light, and forms tomographic image of fundus based on detection results of interference light acquired by the scanning. A setting part sets scan-target location of signal light on distribution information. A specifying part specifies image region in fundus image obtained by the movie imaging that corresponds to the scan-target location. A controller controls the scanner based on the specified image region to carry out scanning of signal light. The tomographic image forming part forms tomographic image from the detection results of interference light acquired by the scanning of signal light based on the control.

主权项

1. A fundus observation apparatus, comprising:
a display configured to display distribution information of examination results of an eye fundus acquired by examination carried out in the past; an imaging optic configured to carry out movie imaging of the eye fundus; a tomographic imager comprising an optical system that generates and detects interference light by superposing signal light returned from the eye fundus on reference light, and a scanner that scans the eye fundus with the signal light, and further configured to form a tomographic image of the eye fundus based on the detection results of the interference light acquired by the scanning; a setting part included within at least one processor including circuitry and configured to set a scan-target location of the signal light on the distribution information displayed on the display; a specifying part included within said at least one processor including circuitry and configured to specify an image region in a fundus image obtained by the movie imaging, that corresponds to the scan-target location; and a programmed controller configured to control the scanner based on the specified image region to carry out the scanning of the signal light, wherein the tomographic imager forms a tomographic image from the detection results of the interference light acquired by the scanning of the signal light based on the control, wherein the specifying part carries out image matching between the displayed image and the fundus image, and specifies an image region in the fundus image that is associated, with the scan-target location in the displayed image, wherein the distribution information includes an image of the eye fundus in which pixel values correspond to the examination results, the specifying part comprises: a second storage configured to previously store two or more image-analysis programs corresponding to two or more types of images; a second type specifying part configured to specify the type of the image displayed on the display; and a second selecting part configured to select an image-analysis program corresponding to the specified type from among the two or more image-analysis programs, and the specifying part carries out said image matching between the displayed image and the fundus image with the selected image-analysis program, and specifies said image region in the fundus image that is associated, by the image matching, with the scan-target location in the display image.
