Ultrasonics - Continuous-Wave Doppler Systems - Test Procedures
|Publication Date:||1 May 1993|
|ICS Code (Electroacoustics):||17.140.50|
This technical report describes:
- test methods for measuring the performance of continuous-wave ultrasonic Doppler flowmeters, velocimeters, or foetal heart detectors;
- special Doppler test objects for determining various performance properties of Doppler ultrasound systems.
This technical report applies to:
- tests made on an overall Doppler ultrasound system; a system which is not disassembled or disconnected;
- tests made on continuous-wave Doppler ultrasound systems. The same tests can be applied to Doppler ultrasound systems which measure position as well as velocity, such as pulsed and frequency-modulated Doppler systems, although additional tests may then be required.
Electrical safety and acoustic output are not covered in this technical report
