Describes test methods for measuring the performance of continuous-wave ultrasonic Doppler flowmeters, velocimeters, or foetal heart detectors. It also describes special Doppler test objects for determining performance properties of Doppler ultrasonic systems. It is identical with and reproduced from IEC 1206:1993.

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
