Title:
血流計測装置
Document Type and Number:
Japanese Patent JP7096116
Kind Code:
B2
Abstract:
To optimize an incident light offset position for measuring an ocular fundus blood flow.SOLUTION: A blood flow measuring device includes a scan optical system, a moving mechanism, an image forming unit, a direction setting unit, a control unit, and a blood flow information acquisition unit. The scan optical system applies an optical coherence tomography (OCT) scan to the ocular fundus of an eye to be examined. The moving mechanism moves the scan optical system. The image forming unit forms an image from first data collected by the scan optical system. The direction setting unit analyzes the formed image and sets a first direction orthogonal to an optical axis of the scan optical system. The control unit applies first moving control for moving the scan optical system in the first direction to the moving mechanism. The blood flow information acquisition unit acquires blood flow information from second data collected by the scan optical system after the first moving control.SELECTED DRAWING: Figure 4
