In clinical imaging, typical frequency ranges are around

• A. 0.1 to 0.5 MHz
• B. 1 to 2 MHz
• C. 2 to 10 MHz
• D. 10 to 20 MHz

Answer: (C)

The main idea is that ultrasound frequency is a balance between resolution and how deep the sound can travel. In everyday clinical imaging, a mid-range frequency band around 2 to 10 MHz is used because it provides enough penetration to image most abdominal and pelvic structures while still giving acceptable detail. Frequencies much lower than this would travel deeper but produce blurry, low-detail images, and frequencies higher than this offer better detail but can’t reach deep tissues well, making them better suited for superficial structures like the thyroid or breasts. So, the typical range you’d rely on for general clinical ultrasound is about 2 to 10 MHz.
