Describes test methods for measuring the performance of continuous-wave ultrasonic Doppler flowmeters, velocimeters, or foetal heart detectors and special Doppler test objects for determining various performance properties of Dopplerultrasound systems. Applies to tests made on an overall Doppler ultrasound system and tests made on continuous-wave Doppler ultrasound systems. The same tests can be applied to pulsed and frequency-modulated Doppler systems, although additional tests may then be required. Electrical safety and acoustic output are not covered.
