This phantom simulates a contrast medium-enhanced head in the arterial phase (CT angiography). It covers the vertex to the foramen magnum.
The phantom has 10 low-contrast lesions in the centrum semiovale and the right hemisphere has an arteriovenous malformation.

The phantom can be used in CT (including CBCT) to evaluate and optimize imaging performance and AI-enabled diagnosis. It is also suited for training purposes. The phantom provides a detailed and realistic simulation of vascular structures, soft and bone tissue. Air voids are filled with a cellulose polymer composite of approx. -160 HU.

Diagnostic features:
• Realistic simulation of head vessels, bone and soft tissues.
• Arteriovenous malformation of the right hemisphere.
• 5 rod-shaped lesions on each side in the centrum semiovale at the periventricular and supraventricular level.
