Computerized segmental plethysmography and laser flowmetry

Abstract A new computerized plethysmograph allows segments of the vascular system to be examined accurately and automatically. Laser flowmetry allows blood flow measurements to be made of digital circulation for vascular abnormalities. With the 2 new instruments, large and small vessel circulations can be measured quickly and easily. Disease of these vessels can be readily detected. Thus, appropriate medical or surgical therapy can be investigated.
