发明名称 OPTICAL IMAGE MEASURING APPARATUS, IMAGE DISPLAYING APPARATUS AND IMAGE DISPLAYING METHOD
摘要 An optical system splits light into signal light and reference light and detects interference light between scattered light of signal light from living body and reference light. A scanner performs first scan in which first cross section that intersects interested blood vessel is repeatedly scanned with signal light. An image forming part forms first cross sectional image expressing chronological variation of morphology of first cross section and phase image expressing chronological variation of phase difference based on detection results of interference light acquired during first scan. A blood vessel region specifying part specifies blood vessel region corresponding to interested blood vessel for first cross sectional image and phase image. A blood flow information generator generates blood flow information related to interested blood vessel based on blood vessel region of first cross sectional image and chronological variation of phase difference within blood vessel region of phase image.

主权项 1. An optical image measuring apparatus, comprising: an optical system configured to split light from a light source into signal light and reference light, and detect interference light between scattered light of the signal light from a living body and the reference light having traveled by way of a reference optical path; a scanner configured to carry out a first scan in which a first cross section that intersects an interested blood vessel in the living body is repeatedly scanned with the signal light; an image forming part configured to form a first cross sectional image that expresses chronological variation of morphology of the first cross section and a phase image that expresses chronological variation of phase difference based on the detection results of the interference light acquired by the optical system during the first scan; a blood vessel region specifying part configured to specify a blood vessel region corresponding to the interested blood vessel for each of the first cross sectional image and the phase image; and a blood flow information generating part configured to generate blood flow information related to the interested blood vessel based on the blood vessel region of the first cross sectional image and the chronological variation of phase difference within the blood vessel region of the phase image.
