リアルタイムレーザースペックル法で得られた血流マップの解析

抄録

A new system, which we call the Real-Time Laser Flowgraphy, have been developed to visualize blood flow in retina using laser-speckle effects. In this paper, we build up a graphical user interface to ease the handling with a mouse operation. Some additional programs are developed to measure the width of the vessels, and to visualize pulsation of the blood flow in 3-D color graphics. The blood flow of human retinal arterioles and veinules are analyzed with this system. It is found that the blood flow evaluated from BR(the Blur Rate of the speckles) is influenced by the width of the vessels.
