How is the test success rate of iLivTouch in obese patients

A

The transient elasticity detection captures the propagation speed of shear wave with ultrasound wave. The fat attenuation is sensitive to ultrasound signals. The attenuation becomes more obvious when the frequency increases. Thick fat on the abdominal wall of obese patients causes a serious attenuation of ultrasound signal when low-frequency shear waves are captured. Then it is impossible to capture the speed of shear wave. It explains the high failure rate of foreign technologies. Our dynamic broadband probe applies ultrasound signals within a wide frequency range (e.g. 1.5M-5Mhz). With such probe, sufficient signals will go deep and return even though the fat layer is thick. It prevents signals attenuating with fat, detects the propagation of shear wave more sensitively and improves the success rate among obese patients.
