Head Phantom

Stroke / Bleed

This phantom simulates a head with stroke and bleeding patterns. It covers the vertex to the foramen magnum.

Stroke patterns include signs of early infarction (hyperdense middle cerebral artery, disappearing basal ganglia), acute and subacute watershed infarcts, and lacunar infarctions of varying ages.

Bleeding patterns include subarachnoid hemorrhage, subdural hemorrhage of varying ages, intraventricular hemorrhage, and intracerebral hemorrhage.

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 common brain pathologies, soft and bone tissues. Air voids are filled with a cellulose-polymer composite of approx. -160 HU.

Diagnostic features

Stroke

• Hyperdense middle cerebral artery (MCA) and disappearing basal ganglia on the left side
• Watershed infarcts in middle/posterior (MCA/PCA) and anterior/middle cerebral artery (ACA/MCA) territories
• 8 lacunar infarcts of varying ages

Hemorrhage

• Subarachnoid hemorrhage (2 territories)
• Subdural hemorrhage of varying ages (3 territories)
• Intraventricular hemorrhage (left lateral ventricle)
• Intracerebral hemorrhage (2 thalamic, 6 subcortical)

CTA

This phantom simulates a contrast medium enhanced head in arterial phase (CT angiography). The neck is included up to the first cervical vertebra. The vertex is included until approximately 0.5 cm below skin level.

The phantom has no significant vascular pathologies.

The phantom can be used in CT (including CBCT) to evaluate and optimize CTA imaging performance and post-processing applications such as vessel segmentation, including AI-enabled applications. It is also nicely suited for training purposes.

The phantom provides a detailed and realistic simulation of vascular structures, soft and bone tissue, including small details such as lymph nodes. Air voids are filled with a cellulose-polymer composite of approx. -160 HU.

Diagnostic features 

Realistic simulation of head vessels up to the first cervical vertebra, bone and soft tissues.

CTA aneurysm

This phantom simulates a contrast medium enhanced head in arterial phase (CT angiography). It covers the vertex to the foramen magnum.

The phantom has three intracranial aneurysms of the middle cerebral artery (MCA), anterior communicating artery (ACoA), and the basilar artery.
