Method and System for Multi-Part Left Atrium Segmentation in C-Arm Computed Tomography Volumes Using Shape Constraints

An apparatus for segmenting a left atrium (LA) in a 3D volume comprising:

• means for segmenting an LA chamber body mesh, an appendage mesh, and a plurality of pulmonary vein (PV) meshes in the 3D volume;
• and
• means for generating a consolidated LA mesh from the LA chamber body mesh, the appendage mesh and the plurality of PV meshes.

A non-transitory computer readable medium encoded with computer executable instructions for segmenting a left atrium (LA) in a 3D volume, the computer executable instructions defining a method comprising:

• segmenting an LA chamber body mesh, an appendage mesh, and a plurality of pulmonary vein (PV) meshes in the 3D volume;
• and
• generating a consolidated LA mesh from the LA chamber body mesh, the appendage mesh and the plurality of PV meshes.
