How is the quality of the ultrasound image affected by the frequency of the sound waves?

• A. Higher frequencies provide lower resolution
• B. Lower frequencies provide higher penetration but lower resolution
• C. Higher frequencies provide higher resolution but less penetration
• D. Frequency does not affect image quality

Answer: (C)

The quality of an ultrasound image is heavily influenced by the frequency of the sound waves used during the imaging process. Higher frequencies produce sound waves that can provide a greater detail and clarity in the images, resulting in higher resolution. This is because higher-frequency sound waves have shorter wavelengths, which can distinguish smaller structures within the body. However, while higher frequencies enhance image resolution, they also have limitations regarding tissue penetration. They do not penetrate as deeply as lower frequencies, which can result in less effective imaging of deeper structures. Understanding this balance is crucial in ultrasound imaging. Clinicians must choose the appropriate frequency based on the specific diagnostic needs—whether prioritizing resolution for superficial structures or penetration for deeper ones. Therefore, the assertion that higher frequencies provide higher resolution but less penetration accurately reflects the relationship between frequency and image quality in ultrasound imaging.
