Methods, apparatuses, and computer programs for processing pulmonary vein computed tomography images
Patent number: 11869208Abstract: The present disclosure relates to methods, apparatuses, and computer programs for processing computed tomography images. Precise segmentation of the left atrium (LA) in computed tomography (CT) images constitutes a crucial preparatory step for catheter ablation in atrial fibrillation (AF). We aim to apply deep convolutional neural networks (DCNNs) to automate the LA detection/segmentation procedure and create a three-dimensional (3D) geometries. The deep learning provides an efficient and accurate way for automatic contouring and LA volume calculation based on the construction of the 3D LA geometry. Non-pulmonary vein (NPV) trigger has been reported as an important predictor of recurrence post atrial fibrillation (AF) ablation. Elimination of NPV triggers can reduce the post-ablation AF recurrence. The deep learning was applied in pre-ablation pulmonary vein computed tomography (PVCT) geometric slices to create a prediction model for NPV triggers in patients with paroxysmal atrial fibrillation (PAF).Type: GrantFiled: March 15, 2021Date of Patent: January 9, 2024Assignees: TAIPEI VETERANS GENERAL HOSPITAL, National Yang Ming Chiao Tung UniversityInventors: Horng-Shing Lu, Chih-Min Liu, Shih-Lin Chang, Shih-Ann Chen, Yenn-Jiang Lin, Hung-Hsun Chen, Wei-Shiang Chen -
