<P>PROBLEM TO BE SOLVED: To provide a fundus oculi blood flow imaging apparatus for precision measurement of blood flow dynamic state. <P>SOLUTION: This imaging apparatus for a blood flow at the fundus oculi is provided with a laser beam irradiation system 1 to irradiate laser beam to blood flow through the biomedical tissues, a beam reception system having a beam receiver composed of many pixels to detect reflected light from the biomedical tissues, an image introducing part to continuously capture a plurality of images at a regular interval based on a signal from the beam receiver, an image memory to store this plurality of images, and an operation part to calculate blood flow velocity within the biomedical tissues from the temporal response of output signals among pixels corresponding to each of different stored images. The laser beam irradiation system is composed of a plurality of laser beam sources generating laser beams with different wavelengths used for the measurement. <P>COPYRIGHT: (C)2009,JPO&INPIT |
