In the past decade, the tremendous advancements in data volume, algorithms, and high-performance computing have propelled artificial intelligence (AI) to the forefront of efficiency. This is especially true in the field of medical imaging and digital pathology, where AI-assisted diagnostic systems have become a focal point of attention in both the academic and medical communities. However, with increasing attention to privacy protection and the perfection of policies and regulations, data sharing has become an urgent issue to address. Federated learning, as a paradigm of “model moving without data moving”, offers a new approach to the privacy protection and data sharing. This paper proposes a federated learning framework that, while ensuring the localization and security of medical imaging data, fully utilizes multi-center pneumonia imaging datasets to train highly accurate AI models to assist in pneumonia image diagnosis. Through localized model training and gradient aggregation on parameter servers, model optimization and updating are achieved without violating data privacy. The outcomes of this study not only improve the accuracy and efficiency of pneumonia diagnosis, but also expand the sample size and data dimensions of the system, providing powerful support for the construction of high-precision models for medical big data applications. This, in turn, helps to provide richer and higher quality medical services, contributing significant value to the development of public medical services. %K 人工智能， %K 医疗影像， %K 联邦学习， %K 图像处理， %K 隐私保护， %K 肺炎影像
