The development of a new intravascular ultrasonic flowmeter enables the measurement of pulsatile blood flow using phase detection and ultrasonic pulse techniques.
May enable experimental pulsatile flow measurements; leaves open clinical validation and safety.
An instrument for the measurement of pulsatile blood flow has been developed. The device uses a small probe suitable for intravascular insertion, and the method of measurement employs a combination of ultrasonic pulse techniques and phase detection.
