| Abstract(in English) | Many studies for quantitative ultrasound (QUS) assessment at frequency band of clinical studies (1-15 MHz) and high frequency band (15-50 MHz) have been reported independently. Additionally, evaluation of acoustic characteristics of biological tissues by ultra-high frequency (50-250 MHz) using scanning acoustic microscopy (SAM) are also progressing, and we aim to understand the acoustic characteristics and scattering characteristics that integrate them. In this study, we evaluated speed of sound (SoS) and attenuation of tissue mimicking phantoms and rat livers in wide frequency band (1-300 MHz), and confirmed the relationship between the acoustic characteristics and the tissue structures. The comprehensively examining protocols the acoustic characterization such as comparing the transmission method and the reflection method, confirming the effect of sample thickness, and comparing raw and fixed samples were systemized, and the problems in each measurement and evaluation method were clarified. |
