Abstract
The invention provides a system for directly imaging and analyzing the movement of individual erythrocytes in blood vessels, the system comprising imaging means (4, 26) for acquiring, within a predetermined time interval from each other, at least one pair of images of at least one same erythrocyte for producing at least two frames, each image representing an analog or digital image of the location of the erythrocyte in each of the frames at a predetermined time; image acquisition means (12) for collecting and storing analog or digital images in machine-readable form, and a computer (10) for controlling the operation of the imaging means and the image acquisition means, for processing the at least two frames, and for analyzing the movement of the erythrocyte in the blood vessels. A method for directly imaging and analyzing the movement of individual erythrocytes in blood vessels is also provided.
