Automatic Segmentation of the Left Atrium from Computed Tomography Angiography Images
Ann Biomed Eng. 2023 Mar 8. doi: 10.1007/s10439-023-03170-9. Online ahead of print.ABSTRACTThe left atrial appendage (LAA) causes 91% of thrombi in atrial fibrillation patients, a potential harbinger of stroke. Leveraging computed tomography angiography (CTA) images, radiologists interpret the left atrium (LA) and LAA geometries to stratify stroke risk. Nevertheless, accurate LA segmentation remains a time-consuming task with high inter-observer variability. Binary masks of the LA and their corresponding CTA images were used to train and test a 3D U-Net to automate LA segmentation. One model was trained using the entire un...
