FattyTouch: A next-generation ultrasound fatty liver diagnosis system that integrates the ultrasound scattering analysis technology developed by Professor Po-Hsiang Tsui's team from the Department of Medical Imaging and Radiological Sciences at Chang Gung University into standard clinical ultrasound systems, achieving a fatty liver diagnosis and evaluation strategy characterized by rapid market adoption, mobile accessibility, simplicity, and effectiveness. FattyTouch provides users with abdominal ultrasound scanning capabilities and objective quantitative analysis of fatty liver severity, thereby enhancing and supporting the diagnostic reliability and subsequent intervention decisions of clinical users to achieve the goal of precision medicine. Furthermore, in alignment with contemporary trends in preventive medicine and comprehensive health platforms, FattyTouch can be utilized to develop fatty liver screening and subsequent long-term health tracking and management platforms. It can also be paired with the development of new drugs for fatty liver treatment to serve as a tool for validating product efficacy.
