This paper proposed a new approach to design medical imaging-sharing service network based on professional medical imaging center (PMIC). PMIC is famous for advanced imaging modalities and expert resources. The network connects clinics, hospitals and PMICs to provide collaborative diagnosis, consultation, mobile expert consulting and medical imaging artificial intelligence (AI) analysis services through Internet. It allows patients to be registered in hospital and examined in PMIC. It provides to schedule and view patients exam from mobile devices. It also provides AI analysis for some specific kinds of medical images such as carotid plaque and mammary cancer, to help doctors get accurate conclusions. The network is flexible to use three layers architecture with secure messaging and data communication: data source, service cloud and service provider. It has been deployed in Guangzhou Huyun Medical Imaging Diagnosis Center since July 2018 to provide services for the First People’s Hospital of Guangzhou.
