The Imaging Display: Part 3
Explore coded excitation techniques and the critical differences between pre-processing and post-processing functions in ultrasound imaging. Understand how fill-in interpolation optimizes spatial resolution for sector-shaped displays and improves signal-to-noise ratios. ARDMS, ARRT, and CCI registry exam preparation.
