EUROLAB laboratory provides testing and compliance services within the scope of EN 61206 standard. It describes test methods for measuring the performance of continuous-wave ultrasonic Doppler flowmeters, accelerometers, or fetal heart detectors, and specific Doppler test objects to determine various performance characteristics of Doppler ultrasound systems.
Continuous wave ultrasonic Doppler flowmeters, accelerometers or fetal heart detectors are widely used in clinical practice.
This type of medical ultrasonic equipment measures the Doppler shift frequency, which is the change in frequency of the ultrasound scattered wave caused by the relative motion between a scattering and ultrasonic transducer. This frequency is proportional to the observed velocity, which is the component of the velocity of a scatterer directed towards or away from the transducer.
This whitepaper describes a range of test methods that can be applied to determine various performance parameters for continuous wave Doppler ultrasound systems. They can also be applied to pulsed Doppler systems, although additional testing is required.
The test methods are based on the use of a number of special devices such as array, tape, disc, piston and flow Doppler test objects. These test methods can be considered to fall into one of the following three categories.
The first are routine quality control tests that can be performed by a clinician or a technologist to ensure that the system is working adequately or has sufficient sensitivity. The second is more detailed testing methods that are conducted less frequently, for example when the system is suspected. Third, it represents testing on complete systems by a manufacturer as the basis for the type specification of performance.
