Description
A technique for quantitation of the elastic characteristics of the aorta in vivo has been developed and tested in dogs and humans. The method depends upon angicardiographic data recorded with a video system to quantitative pulsatitel changes in vascular size. From such measurements of diameter and simultaneous intravascular pressure recorded at the same point in the aorta, vascular elasticity may be calculated. The data reduction method is unique and represents the prime contribution of this thesis. System noise was reduced with the aid of a digital computer averaging technique. Advantages and limitations ot the method are discussed and data from experimental animal and human subject are presented to demonstrate its practicality.
