DOI: 10.1109/tim.2023.3332397

Abstract: Contrast-enhanced harmonic imaging has shown unique advantages in identifying micro-vasculature for tumor characterization. Recent studies indicate that the third to fourth harmonics are the optimal ranges to detect microbubble contrast agents in microvessels. However, it… read more here.
