A method for detecting a rib with a medical image, a device and a medium are provided. Feature coding is performed, by using a neural network model, on different rib regions in the medical image to obtain multiple feature vectors. According to a learned corresponding relationship between rib query items and the different rib regions, a feature vector for respective rib query item is determined. Parallel decoding is performed on the feature vector for respective rib query item to obtain a rib detection result corresponding to respective rib query item. The rib query items are endowed with semantic information in anatomy, such that respective rib query items may focus on features of different rib regions, and thus realizing controllable rib detection in instance-level. Any rib detection result includes a rib prediction classification and a prediction value of a pose parameter, in a three-dimensional space, of a rib detection box.
