Quantitative ultrasound technique utilizes the amplitude and frequency dependence of the backscatter coefficient (BSC) to estimate the size and concentration of scatterers. QUS techniques rely on theoretical scattering models to fit the BSC from biological tissues to an estimated BSC using an appropriate model. Franceschini and Guillermin (J....

Ultrasonic backscatter coefficient (BSC) measurements were performed on K562 cell pellet biophantoms with cell concentrations ranging from 0.006 to 0.30 in the 10-42 MHz frequency bandwidth. Three scattering models, namely the Fluid-Filled Sphere Model (FFSM), the Particle Model (PM) and the Structure Factor Model (SFM), were compared for...
