Computer capillaroscopy as a new cardiological diagnostics method

The blood flow in capillary vessels plays an important role in sustaining the vital activity of the human organism. The computerized capillaroscope is used for the investigations of nailfold (eponychium) capillary blood flow. An important advantage of the instrument is the possibility of performing non-invasive investigations, i.e., without damage to skin or vessels and causing no pain or unpleasant sensations. The high-class equipment and software allow direct observation of capillary blood flow dynamics on a computer screen at a 700 - 1300 times magnification. For the first time in the clinical practice, it has become possible to precisely measure the speed of capillary blood flow, as well as the frequency of aggregate formation (glued together in clots of blood particles). In addition, provision is made for automatic measurement of capillary size and wall thickness and automatic recording of blood aggregate images for further visual study, documentation, and electronic database management.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
