Description
Dynamic Adult Human Head Phantom is designed to be suitable for medical imaging of blood flow underneath the skull. The phantom is designed based on an average anatomy of a human male head and it is made out of realistic soft and hard tissue mimicking materials suitable for Ultrasound, MRI and CT applications.
The phantom consists of the following components:
- Anatomically correct realistic skull
- Realistic brain parenchyma (Gray matter)
- Complex brain vessels incorporated Circle of Willis
- One bifurcation
- One stenosis
- Two aneurysms
- Connecting vessels with the neck
- Plastic connectors
- Implementing a surrounding, acoustically correct skin-mimicking material to the skull phantom (the phantom will have the appearance of an actual human head)
