Research on the fusion method of 2D and 3D UNet in pulmonary nodules segmentation task

In segmentation task of pulmonary nodules CT image, the U-shaped convolution neural network (UNet) has made great progress in segmentation accuracy and stability. However, for the three-dimensional (3D) connection characteristics of medical sequence slices, 3D segmentation networks often can’t give full play to their potential and advantages constrained by such factors as the number of marked samp...
