Since the outbreak of COVID-19 in China, our hospital has undertaken a large number of work to screen potential COVID-19 risks in the district, and has diagnosed hundreds of suspected cases. In order to strengthen the protection of first-line medical staff in the Department of Radiology during the epidemic, the clinic was armed with medical equipment, providing a solid foundation for overcoming the epidemic. Based on relevant research on the national epidemic situation, an intelligent system was constructed to reduce personnel contact and avoid cross infection. Through the intelligent interactive system, the clinical medical staff in the Department of Radiology were effectively protected. So far, no one has been infected. Clinical engineers could protect the safety of medical staff through scientific anti-epidemic practice and continuous optimization of work.
