Abstract: With the development of computer technology, the role of artificial intelligence in the medical field has become increasingly prominent. Especially in recent years, the new type of intelligent impact recognition robot assists doctors in disease diagnosis, which greatly improves the efficiency of doc-tors’ diagnosis. This paper mainly studies the image recognition accuracy of the neural network model affected for CT. This article takes the lung CT images of patients with new coronary pneumo-nia as the research object. Feature extracti...
