Diagnosis and assessment of liver fibrosis grade required for management is mainly based on blood tests and invasive hepatic puncture-biopsy. Quantitative UltraSound (QUS) techniques provide insight into tissue microstructure and are based on the frequency-based analysis of the signals from biological tissues. This study aims to explore the diagnostic performance of QUS technique in high frequency...
We propose in this study a contrast agent detection method based on a multi-frequency excitation. In fact, the frequency dependency of microbubbles linear scattering is known to differ significantly from the one of tissue. The method was evaluated using an open scanner with analog transmitters. In vitro experiments were performed using a 3.5 MHz single element in transmit. Gaussian pulses at 2.5 MHz,...
