Frequently Asking Questions
  • What is a unidirectional Doppler?

    A unidirectional Doppler ascertains the flow velocity without directional information. That means you cannot decide if the blood is flowing toward or away from the ultrasound probe.

    Please refer to our brochure "The Doppler Sonography in Vascular Diagnostics" for more information.
  • What is a bidirectional Doppler?

    A bidirectional Doppler ascertains the flow velocity including directional information. That means you can decide if the blood is flowing toward or away from the ultrasound probe. If the ultrasound probe simultaneously covers a vein and an artery, the flow velocities from both blood vessels are independently ascertained and displayed.

    Please refer to our brochure "The Doppler Sonography in Vascular Diagnostics" for more information.
  • How can ultrasound probes be cleaned?

    The ultrasound probes can be cleaned and disinfected. Please refer to the operating instructions for in-depth information.
