Questions and Answers

How do different tissues interact with ultrasound waves?

  • All tissues reflect the waves directly
  • All tissues scatter the waves before reflecting them
  • Some tissues reflect directly while others scatter the waves (correct)
  • All tissues absorb the waves completely

    • What is the frequency range of ultrasound waves?

  • 20 Hz - 200 Hz
  • 500 Hz - 5 kHz
  • 20 kHz - Inaudible to humans (correct)
  • 100 kHz - 200 kHz

    • Why do echoes from deep within the body need more amplification?

  • They are more attenuated compared to echoes from superficial parts (correct)
  • They are naturally louder echoes
  • Deep echoes are closer to the transducer
  • They require less energy to amplify
