A proposed 2 s automated left atrial wall segmentation from 3D late gadolinium enhancement imaging using deep learning provided comparable segmentation performance to 16-30 min manual segmentation.
Figure 3. Examples of results for the different DL networks from four testing cases. The segmentation results generated by the 3D inputs are qualitatively better than those generated by the 2D inputs.
Figure 2. The overall process of DL segmentation for (A) 2D and (B) 3D inputs. The LA LGE and reference masks extracted from manual contours were used as input and reference to train the DL network. For testing, the LA LGE images were fed into the trained network to get the DL segmented masks.
