Fusing 2D and 3D convolutional neural networks for the segmentation of aorta and coronary arteries from CT images

作者：

Highlights：

• We propose a two-stage strategy that retains the advantages of both 2D and 3D CNNs.

• The strategy is applied to segment the aorta and coronary arteries from CT images.

• The 3D CNN improves the inter-slice continuity and reduces the missed detection rate.

• This strategy can alleviate the class imbalance problem and reduce the training time.

• Extensive experiments are carried out to validate the efficacy of our method.
