What is the primary reason for the low quality of ultrasound images from low-frequency waves?
Understand the Problem
The question is asking for the main factor that contributes to the poor quality of ultrasound images produced by low-frequency sound waves, and presents multiple choice options to analyze.
Answer
Long wavelength results in lower resolution, reducing image quality.
The primary reason for low quality in ultrasound images from low-frequency waves is their long wavelength, which results in lower resolution.
Answer for screen readers
The primary reason for low quality in ultrasound images from low-frequency waves is their long wavelength, which results in lower resolution.
More Information
Low-frequency ultrasound waves have a long wavelength, which provides poor resolution. This means they cannot distinguish small structures, although they offer better penetration for imaging deeper tissues.
Tips
A common mistake is to assume low-frequency waves produce better images due to their ability to penetrate deeper. Remember that penetration and resolution are trade-offs.
