Body part: Brain with arterial ring, and base of brain

Special features: contains aneurysms, embedded in base of skull with craniotomy

Use: advanced training, neurosurgical training, medical technology demonstrations

Accessories: Skull and brain model separate

Process: 3D print from digital anatomical material with a realistic feel, commercially available skull model made of plastic

The model of the base of brain with Circulus Willisii and aneurysms, is a 3D-printed replica, based on patient-specific DICOM data from a CT scan. The used tissue material is prerequisite for realistic material properties such as flexibility, wall tension and slip behavior in a moist environment. The arteries are semi-transparent and have a wall thickness of approx. 1.5 mm and an inside diameter of approx. 2 - 3 mm. The brain is embedded in a commercially available skull with temporal craniotomy, above which the Circulus Willisii with aneurysm is visible.
