scope:

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
