BLOOD FLOW INFORMATION GENERATION APPARATUS, BLOOD FLOW INFORMATION GENERATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform blood flow measurement with high accuracy.SOLUTION: A blood flow information generation apparatus comprises an acquisition unit, a blood vessel region identification unit, and a blood flow information generation unit. The acquisition unit acquires a tomographic image showing time-series variation of a form of a cross section crossing a target blood vessel of a living body, which is formed by executing optical coherence tomography (OCT) to the cross section, and a phase image showing time-series variation of a phase difference. The blood vessel region identification unit identifies blood vessel regions corresponding to the target blood vessel for each of the tomographic image and the phase image. The blood flow information generation unit generates blood flow information on the target blood vessel on the basis of the blood vessel region of the tomographic image and the time-series variation of the phase difference in the blood vessel region of the phase image.SELECTED DRAWING: Figure 3
