What is the typical range of frequencies used in ultrasound imaging?

• A. 10 to 100 kHz
• B. 1 to 20 MHz
• C. 20 to 50 kHz
• D. 1 to 10 GHz

Answer: (B)

Ultrasound imaging operates within a frequency range that allows for optimal penetration and resolution of soft tissues in the body. Frequencies between 1 to 20 MHz are particularly effective for medical ultrasound applications such as obstetric or abdominal imaging. Within this range, higher frequencies yield better resolution images, making them suitable for applications like cardiac imaging, while lower frequencies are utilized for deeper tissue penetration in larger patients or for imaging structures like the liver or kidneys. This specific frequency range is essential for producing high-quality images that medical professionals rely on for diagnostics and treatment planning.
