Background, Motivation and Objective Choosing an appropriate dynamic range for acquiring radio-frequency (RF) data from a high-frequency ultrasound (HFU) system is challenging because signals can vary greatly in amplitude as a result of focusing and attenuation effects. In addition, quantitative ultrasound (QUS) methods are sensitive to saturated data. This study quantified saturation effects on effective scatterer diameter (ESD) and effective acoustic concentration (EAC). A representative dataset consisting of 82 dissected human lymph nodes included 22 metastatic lymph nodes was used and 3D RF data were acquired from these lymph nodes using a single-element transducer operating at a center frequency of 26 MHz.
