[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is further described in detail.
[0059] The technical issues concerned by the present invention are: how to use computer to automatically, efficiently and accurately detect pulmonary nodules in multi-resolution CT images; at the same time, how to judge the properties of pulmonary nodules through multiple influence omics features. In order to solve the above technical problems, the present invention provides a method for detecting CT pulmonary nodules using a deep convolutional neural network. This method uses a target detection method based on a region proposal network when obtaining candidate pulmonary nodules. The network structure uses a three-dimensional residual network as feature extraction, and the learning error includes regression error and classification error. The model is iteratively updated using data of different layer thicknesses, and co...
