The basic concept of the proposed novel aneurysm volume quantification method. Digital Imaging and Communications in Medicine data is converted to the 3-dimensional (3D) model and exported to a 3D STL file format. This 3D to stereolithography (STL) model is modified to reach the normal vasculature. The volume difference between 3D STL model with/without the aneurysm is defined as the aneurysm volume.
