Abstract

To accurately diagnose multiple pathological types of pulmonary nodules based on lung computed tomography (CT) images, a multi-resolution three-dimensional (3D) multi-classification deep learning model (Mr-Mc) was proposed. The Mr-Mc model was constructed by using our own constructed lung CT image dataset of pulmonary nodules with clinical pathological information (LCID-CPI), which can accurately diagnose inflammation, squamous cell carcinoma, adenocarcinoma, and other benign diseases. In order to process nodules with different sizes, a multi-resolution extraction method was proposed to extract 3D volume data with different resolutions from lung CT images. The Mr-Mc was composed of three different resolution networks, each of which has input volume data of a specific resolution. Experiments showed that the constructed Mr-Mc model can achieve an average accuracy of 0.81 on LCID-CPI. Besides, the Mr-Mc model can also achieve a high accuracy of 0.87 on the Lung Image Database Consortium and Image Database Resource Initiative dataset.
