What is the dynamic broadband technology used in FibroTouch?

A

1. The term “dynamic” indicates that the range of liver elasticity is determined dynamically. Among signals received by fiber scanning probe, the cortex signal is obviously different from the liver signal. The cortex signal amplitude is larger and concentrated while the liver signal amplitude is smaller and uniform between layers. With proprietary algorithm, FibroTouch can identify the interface between liver and cortex among different patients dynamically and then select liver tissues 1cm to 5cm below the interface to calculate the liver elasticity. So, it is said that FibroTouch provides a dynamic detection range of liver fibrosis for various patients.

2. When it comes to the broadband technology, FibroTouch utilizes the broadband probe technology to send ultrasound signals within a frequency range wider than traditional ones (2.5Mhz or 3.5Mhz). And these ultrasound signals contain both low-frequency and high-frequency ultrasound signals. Low-frequency signals can guarantee the depth of signal while high-frequency signals can assure the spatial resolution. Therefore, FibroTouch can apply one probe to different patients, even to obese patients. The reason is that the broadband technology reduces the attenuation of signal and maintains the success rate of detection.
