Ultrasound frequency trade-offs
Switching from a 3 MHz to a 10 MHz ultrasound probe will:
Answer C: explanation for every choice
A
Higher frequencies are attenuated faster, so penetration falls.
B
This describes switching to a lower frequency.
C
Correct. Shorter wavelengths resolve finer detail but are absorbed more quickly by tissue.
D
The speed is the same, but wavelength changes with frequency, which affects both resolution and absorption.
TakeawayHigher ultrasound frequency → better detail, shallower depth.
