Ultrasound Interactions
Overview
This lecture explains how ultrasound images are produced through interactions with tissue. It covers key processes such as reflection, scattering, attenuation and refraction, helping users understand how these factors affect image quality and interpretation.
Learning outcomes
By the end of this lecture, you should be able to:
-
Explain how ultrasound interactions with tissue contribute to image formation, including reflection, scattering, absorption, and refraction.
-
Describe the role of variations in acoustic impedance in determining image appearance.
-
Describe the impact of ultrasound frequency on penetration and spatial resolution and relate these to your choice of probe and clinical image optimisation.
-
Apply the principles of pulse-echo imaging to explain range determination and axial and lateral resolution in B-mode ultrasound imaging.
