PROBLEM TO BE SOLVED: To provide technique allowing high-accuracy blood flow measurement.SOLUTION: An optical image measurement system includes an optical system, a scanning part, an image formation part, a blood vessel region specific part, and a blood flow information generation part. The optical system divides light from a light source into signal light and reference light, and detects interference light between the scattered light of the signal light by a living body and the reference light passing through a reference light path. The scanning part performs first scanning repeatedly scanning a first cross-section crossing a notice blood vessel of the living body by the signal light. The image formation part forms a first tomographic image representing a time-series change of a form in the first cross-section and a phase image representing a time-series change of a phase difference, based on a detection result of the interference light obtained by the optical system in the first scanning. The blood vessel region specific part specifies a blood vessel region corresponding to the notice blood vessel about each of the first tomographic image and the phase image. The blood flow information generation part generates blood vessel information related to the notice blood vessel based on the blood vessel region of the first tomographic image and the time-series change of the phase difference in the blood vessel region of the phase image.COPYRIGHT: (C)2013,JPO&INPIT【課題】血流計測を高確度で行う。【解決手段】実施形態の光画像計測装置は、光学系、走査部、画像形成部、血管領域特定部及び血流情報生成部を有する。光学系は、光源からの光を信号光と参照光とに分割し、生体による信号光の散乱光と参照光路を経由した参照光との干渉光を検出する。走査部は、生体の注目血管に交差する第1断面を信号光で反復的に走査する第1走査を行う。画像形成部は、第1走査において光学系により得られる干渉光の検出結果に基づいて、第1断面における形態の時系列変化を表す第1断層像と位相差の時系列変化を表す位相画像とを形成する。血管領域特定部は、第1断層像及び位相画像のそれぞれについて、注目血管に対応する血管領域を特定する。血流情報生成部は、第1断層像の血管領域と位相画像の血管領域における位相差の時系列変化とに基づいて、注目血管に関する血流情報を生成する。【選択図】図3
