3D Automatic Segmentation of Aortic Computed Tomography Angiography Combining Multi-View 2D Convolutional Neural Networks
2020
Cardiovascular Engineering and Technology
Preserved Fulltext
To overcome the limitations given by manual and semi-automatic segmentation tools, we apply a deep learning-based pipeline to automatically segment the CTA scans of the aortic lumen, from the ascending ...
The achieved results show that the proposed pipeline can effectively localize and segment the aortic lumen in subjects with aneurysm. ...
