Utilize the appropriate duplex instrumentation with the appropriate frequencies for the vessels being examined:

• Typically, a linear 5-7 MHztransducer
  • Superficial structures may require a higher frequency transducer.
  • Deeper structures or edematous tissue may require a lower frequency transducer.
  • Ilio-caval imaging requires a lower frequency, 2-5 MHz curvilinear or phased array transducer.
• Display of two-dimensional structure and motion in real-time
  • Doppler ultrasonic signal documentation
  • Spectral analysis with color and/or power Doppler imaging
• Digital storage of static images and/or cineloop is required
