Title:
【発明の名称】微小気泡による流体に対する超音波マノメトリー
Document Type and Number:
Japanese Patent JPH03500010
Kind Code:
A
Abstract:
The invention relates to an ultrasonic manometry process in a fluid containing stabilized micro bubbles in an ensemble, wherein ultrasonic impulses are radiated into the fluid and brought to interact with the micro bubbles. The amplitude and/or frequency alterations in the ultrasonic scatter signals are recorded and evaluated compared with the ultrasonic impulses radiated in and/or previously recieved. Preparations for measuring blood pressure which can be used with the manometry process are described.
