Evaluate Patients With Chronic Hepatitis by Three-dimensional Force-controlled Ultrasound Measurement

Ultrasound (US) B mode image is an alternative method to measure tissue structure and has proven to be an accurate technique to measure subcutaneous fat thickness. However, pressing the transducer onto the skin with too much force will significantly reduce the subcutaneous adipose tissue thickness. In this study, a force controlled system combined with US transducer was used for 3D subcutaneous fat imaging and reconstruction.
