19 June 1979 Cardiac Blood Flow Measurement: A Component Of The Comprehensive Cardiac Examination
Author Affiliations +
Quantitative noninvasive assessment of cardiac physiologic variables in a clinical setting is a desirable yet technically difficult goal. The classical param-eters of interest include chamber or vessel pressures, ventricular dimensions and volumes, and blood flow. Ultrasonic techniques have demonstrated the potential for dimension and flow detection; however, direct noninvasive pressure measure-ments are still beyond the state of the art for this modality. The Ultrasound Program at the University of Washington has-as its major goal the development and application of new ultrasonic technologies to the problem of quantitative cardiovascular assessment. The current status of this program will be reviewed with particular emphasis on cardiac applications. Experience gained from similar pe-ripheral vascular applications will be used to demonstrate the approach. A real-time computer-based ultrasound system with specialized displays is being developed. Components of this system include real-time cross-sectional imaging, pulsed Doppler flow detection and imaging, transducer position locator devices, digital image storage and display units and microprocessor-based signal analysis techniques.
