Head phantom “Aneurysm” for CT, X-ray and radiation therapy

This phantom simulates a contrast medium enhanced head in arterial phase (CT angiography). The neck and upper thorax are included up to the aortic arch and the fifth thoracic vertebra.The vertex is included until approximately 0.5 cm below skin level. The thoracic phantom section excludes shoulder and back parts that are typically not part of CTA examinations.The internal carotid artery has calcifications on both sides with moderate stenosis on the right side. Otherwise, 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 tissues. Air voids are filled with a cellulose-polymer composite of approx. -160 HU.Diagnostic features• Realistic simulation of head and neck vessels up to the aortic arch, bone and soft tissues.• Calcifications of the internal carotid artery at the carotid bifurcation on both sides with mild stenosis on the right side.

This phantom simulates a contrast medium enhanced head in arterial phase (CT angiography). It covers the vertex to the fifth cervical ver¬tebra. 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. Size (mm): 186 x 224 x 269 mm

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 featuresStroke:• Hyperdense middle cerebral artery (MCA) anddisappearing basal ganglia on the left side• Watershed infarcts in middle/posterior(MCA/PCA) and anterior/middle cerebralartery (ACA/MCA) territories• 8 lacunar infarcts of varying agesHemorrhage• Subarachnoid hemorrhage (2 territories)• Subdural hemorrhage of varying ages (3 territories)• Intraventricular hemorrhage (left lateral ventricle)• Intracerebral hemorrhage (2 thalamic, 6 subcortical)

This phantom simulates a contrast medium enhanced head in 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 cellulosepolymer 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.
