It is now possible to reconstruct patient-specific models of arterial geometries, and to use these models to obtain detailed information about in vivo hemodynamics. Several methods can be used to obtain such patient-specific arterial geometries, including in vivo medical imaging, vascular casting and pressure fixation of vessels. Ideally, any of these methods, when applied to a single artery, would yield the same ‘true’ arterial geometry. The objective of this study was to test this supposition.
