Precise anatomical localization and classification of rib fractures on CT using a convolutional neural network

•A novel CNN model can automatically detect and output the precise anatomical localization and classification of rib fractures.•The sensitivity of localization reached 94.87% and 97.11% in the right and left ribs, respectively.•The CNN model had a certain robustness verified by the external test, and it matched or surpassed the detection and classification performance of experienced radiologists.
