In chemical and food industry, the fluid concentration distribution inspection plays a key role in the control of the production processes. To meet the requirement of process control and by-product reaction suppression in chemical and food industry, advanced fluid concentration measurement techniques are highly desired. Due to its nondestructive and non-radiation features, Ultrasonic tomography (UT) is considered as a promising technique for monitoring the sucrose solution in the container, yielding images of both sound velocity and concentration. In this paper, we investigate the potential of using ultrasound tomography for quantitative fluid concentration imaging. Theoretical Basics of ultrasound tomography are studied, emphasizing aspects of tomographic forward problem, time-of-flight estimation, and the tomographic reconstruction algorithm. The feasibility and effectiveness of the developed methods are validated in numerical simulations.
