Contrast-Enhanced Ultrasound Imaging with Chirps: Signal Processing and Pulse Compression [PDF]

, 2015
Contrast-enhanced ultrasound imaging creates one of the worst case scenarios for pulse compression due to depth and frequency dependent attenuation, high level of harmonic generation, phase variations due to resonance behavior of microbubbles, and ...
