What is the frequency range used in the ultrasound concepts discussed?

• A. 0-20 MHz
• B. 2-15 MHz
• C. 1-10 MHz
• D. 5-20 MHz

Answer: (B)

In diagnostic ultrasound, frequency is picked to balance how deep the sound can travel with how clearly it can image details. Higher frequencies give sharper images but don’t penetrate as far; lower frequencies go deeper but lose resolution. A practical, widely used range for general ultrasound imaging is about 2 to 15 MHz. This span lets you image deeper structures like the abdomen while still providing good detail for superficial tissues and organs. The other options either start too low or end too high to cover the typical range used across common ultrasound applications, or they include impractical ends. That’s why 2–15 MHz best fits the discussion.
