Abstract:
1. A method of segmenting at least one of a pulmonary artery, a pulmonary vein and a left atrial appendage in a 3D volume, comprising: segmenting at least one of a pulmonary artery shape model, a pulmonary vein shape model, or a left atrial appendage shape model in the 3D volume, wherein segmenting at least one of a pulmonary artery shape model, a pulmonary vein shape model, or a left atrial appendage shape model in the 3D volume comprises at least one of: generating at least one of a pulmonary artery mask, a pulmonary vein mask, and a left atrial appendage mask by locally refining the segmented at least one of a pulmonary artery shape model, a pulmonary vein shape model, and a left atrial appendage shape model based on local voxel intensities in the 3D volume.
