Abstract
(EN)

PROBLEM TO BE SOLVED: To automate the setting of a measurement site of eyeground blood flow.

SOLUTION: A blood flow measurement device according to an exemplary embodiment of the invention includes a scan optical system, a front image acquisition unit, a region of interest setting unit, a scan control unit, and a blood flow information acquisition unit. The scan optical system applies an optical coherence tomography (OCT) scan to the eyeground of a subject eye. The front image acquisition unit acquires a front image of the eyeground. On the basis of a preset condition, the region of interest setting unit analyzes the front image and sets a region of interest intersecting a blood vessel. The scan control unit controls the scan optical system to apply repetitive OCT scans to the region of interest. On the basis of data collected by the repetitive OCT scans, the blood flow information acquisition unit acquires blood flow information.

【課題】眼底血流の計測位置の設定を自動化する。
【解決手段】例示的な実施形態に係る血流計測装置は、スキャン光学系と、正面画像取得部と、注目領域設定部と、スキャン制御部と、血流情報取得部とを含む。スキャン光学系は、被検眼の眼底に光コヒーレンストモグラフィ(OCT)スキャンを適用する。正面画像取得部は、眼底の正面画像を取得する。注目領域設定部は、予め設定された条件に基づき正面画像を解析して、血管に交差する注目領域を設定する。スキャン制御部は、注目領域に対して反復的OCTスキャンを適用するようにスキャン光学系を制御する。血流情報取得部は、反復的OCTスキャンにより収集されたデータに基づいて血流情報を取得する。
