As a safe, non-invasive, intuitive and simple diagnostic method, ultrasound has become one of the necessary clinical diagnostic equipment. With the rapid development of medical information technology, higher requirements have been placed on the convenience and intelligence of ultrasound. At the same time, traditional large-scale desktop ultrasound equipment cannot cover tens of thousands of township health centers in China, as well as more village-level health institutions. The domestic medical industry urgently needs small ultrasound equipment that can be used clinically. As a world-leading technology health medical platform, developing a low-cost, multi-functional, high-reliability, easy-to-maintain, and easy-to-use mobile ultrasound diagnostic system has become an urgent need.
