A New Noninvasive Technique For Cardiac Pressure Measurement II: Scattering From Encapsulated Bubbles
Additional Document Info
In a recent paper a new technique for a noninvasive measurement of cardiac pressure utilizing tiny air bubbles was proposed and researched. In the present paper we report on the amplitude and frequency sensitivity to pressure of two types of spheres. Further, we demonstrate the viability of the proposed scheme as applied to remote cardiac pressure measurements. 1979 SPIE.
