# 4. Device Description

The proposed device is a general purpose, mobile, software-controlled, diagnostic ultrasound system. It consists of a fibrosis scanning probe, an imaging probe, a main unit, a probe holder, an AC/DC adapter and a foot switch. The

{5}

fibrosis scanning probe is a single element probe used for elasticity measurement, while the imaging probe is a convex probe used for ultrasound imaging. The system uses transient elastography to measure shear wave speed non-invasively and estimates of tissue stiffness as well as Ultrasound Attenuation Parameter (UAP) in internal structures of the body. A mechanical vibrator in the fibrosis scanning probe produces low-frequency shear waves at 50 Hz that travel through the skin and intercostal space into the liver. The propagation speed of the shear wave is captured using ultrasound at 2.5 MHz. Under imaging mode, the system acquires and displays ultrasound images in B,M,CFM,PWD modes. The system uses imaging probe with nominal Frequency of 2.5-4.5 MHz on abdomen for general purpose pulse echo ultrasound imaging and Doppler flow analysis of the human body. The ultrasonic imaging also helps to find a proper location for the transient elastography examination.

There are a total of 9 models in this product, all of which share the same intended use, physical design and principle of technology. The only differences among these models are software functions configuration and availability of imaging probe.
