Angiographic methods for blood flow measurements. 1976

S Yerushalmi, and Y Itzchak

Radiopaque angiographic contrast agents are being used as indicators for the measurement of blood flow; the basic assumption for these measurements being that both blood and indicator flow nearly at the same rate. Indicators are injected into the circulation and recorded immediately by X-ray filming or video techniques; density changes at selected points along the recorded vessel are detected; dilution curves are plotted and blood flow is calculated graphically or by computer.

D014465	Ultrasonics	A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues.	Ultrasonic
