Deep Small Bowel Segmentation with Cylindrical Topological Constraints [article]

Seung Yeon Shin, Sungwon Lee, Daniel C. Elton, James L. Gulley, Ronald M. Summers
2020 arXiv   pre-print
We present a novel method for small bowel segmentation where a cylindrical topological constraint based on persistent homology is applied.  ...  To address the touching issue which could break the applied constraint, we propose to augment a network with an additional branch to predict an inner cylinder of the small bowel.  ...  The added parts of the network enable the correct application of the cylindrical topological constraint for small bowel segmentation during training.  ...

A persistent homology-based topological loss for CNN-based multi-class segmentation of CMR [article]

Nick Byrne, James R Clough, Isra Valverde, Giovanni Montana, Andrew P King
2021 arXiv   pre-print
Multi-class segmentation of cardiac magnetic resonance (CMR) images seeks a separation of data into anatomical components with known structure and configuration.  ...  Building an enriched topological description of all class labels and class label pairs, our loss functions make predictable and statistically significant improvements in segmentation topology using a CNN-based  ...  Works have considered the topologies of the branching murine neurovasculature [33] , the cylindrical small bowel [34] and the toroidal appearance of the myocardium in short axis CMR [35, 36] .  ...
