Left Atrium Cavity and Wall Segmentation

Left Atrium segmentation from LGE-MRI is the initial step for diagnosing left atrial fibrosis. However, because of the varying image quality and the different shapes of the left atrium, deep learning methods are gaining more attention on left atrium segmentation. So, we analyzed the deep learning models that perform well on medical imaging on MICCAI 2018 left atrium segmentation challenge dataset. After evaluating different metrics, the analysis shows that deep learning models with skip connection or self-attention-based models perform better on average in all metrics than other deep learning architectures. Apart from that LA wall segmentation was also implemented on University of Utah's LGE-MRI dataset. This research can be reference for other medical imaging analysis.
