How does the ultrasound frequency affect the image depth?
How does the ultrasound frequency affect the image depth?
Homework Answers
The higher the frequency of ultrasound, the more will be attenuation and therefore the depth of tissue/image penetration will be less (because absorption is directly proportional to frequency of ultrasound and therefore more is frequency more will be absorption by tissue and less will be penetration). Therefore high frequency of ultrasound is used to view superficial structure.
Note - High frequency of ultrasound produce high resolution (details) image.
