Adult Head (Standard)

Description

Adult Head (Standard) phantom is visible on Ultrasound, MR and CT scans. The brain parenchyma inside of the skull phantom is made of an ultra-soft polyurethane-based material that mimics soft tissue and its anatomical shape was created based on the optical scan of an average human brain model used in the anatomy class for medical students. The materials used to build the phantom are stable over time and they do not dry out.

The phantom consists of following components:

• Anatomically correct realistic skull
• Realistic brain phantom
• Water fillable brain ventricles
• Brain tumor
• Blood vessels with one bifurcation
• Falx cerebri
• Skin implemented to the skull

The phantom comprises the entire ventricular system (lateral, third and fourth ventricles) which can be used to generate pressure inside the brain, and more closely approximate real cerebral anatomy. The ventricles are inflatable and can be filled with any liquid.

Prior to imaging the phantom please fill the ventricles completely with water (or chosen contrast agent) using the tube on the back of the brain. After the ventricles are filled, plug the tube with a removable blue silicone plug.
