Topographic Elasticity Measurement for an Estimation of Hepatic Fibrosis Using Tactile Mapping System
In this study, a tactile mapping system was developed to obtain a two-dimensional elasticity distribution image in order to study the cause of hardening of a chronic hepatitis and liver cirrhosis. Tactile Mapping system utilized a micro tactile sensor which can measure a local elasticity of a very thin sample in micron scale. By comparing the tactile mapping image and azan stained image, it was indicated that the accumulation of the collagen might be the main cause of the liver hardening
