Title: .stl file of Circle of Willis Open Access Deposited

Benchmark geometric model for hemodynamic simulation software

h
Attribute Value
Methodology
  • The .stl file of the main arteries in the Circle of Willis was created from Computed Tomography Angiography (CTA) data using a segmentation procedure whereby the arterial lumen boundary was defined using a combination of manual demarcation, image thresholding, and level-set segmentation [1,2]. A set of vessel centerline paths and 2-D segmentations along each path were produced; from these a 3-D geometric solid model defined by non-uniform rational B-splines (NURBS) was created.

Description
  • This .stl file represents the largest vessels of the cerebral circulation, specifically around the Circle of Willis. The file was created from a Computed Tomography Angiography (CTA) of a relatively healthy patient. It consisted of a 512 x 512 x 709 voxel image with a resolution of 0:35 mm x 0:35 mm x 0:5 mm. The model includes the basilar artery (1), left and right internal carotid arteries (2, and 3), left and right anterior cerebral arteries (4, and 5), left and right middle cerebral arteries (6, and 7), left and right posterior cerebral arteries (8, and 9), and various communicating arteries (10, 11, and 12).
