## Indications for use
The Liverscan Mobile is intended to provide shear wave speed measurements and estimates of tissue stiffness as well as ultrasound coefficient of attenuation (MAP: Mobile Attenuation Parameter) in internal structures of the body. The shear wave speed and stiffness measurements may be used as an aid to clinical management of adult patients with liver disease. The Liverscan Mobile is indicated for non-invasive measurement in the liver of 50 Hz shear wave speed and estimates of stiffness as well as determining a 3.5MHz ultrasound coefficient of attenuation (MAP: Mobile Attenuation Parameter). The shear wave speed and stiffness, and MAP may be used as an aid to diagnosis and monitoring of adult patients with liver disease, as part of an overall assessment of the liver. This device is designed to be used in a doctor's office to measure the stiffness and ultrasonic attenuation of the liver in patients with liver disease. It does so in a painless and completely non-invasive manner. To ensure safe and effective operation,the operator shall meet the following requirements: 1) Receive training as required by local,state and national regulations,if applicable 2) Receive additional training as required by the authorized distributor or EIELING 3) Has a thorough knowledge and understanding of the material presented in this manual
