Angiographic Head Phantoms
|
The
Anthropomorphic Quality Assurance Phantom
3-Dimensional high-contrast vascular pattern
Full or half-head
Tissue equivalent materials
Stepwedge and resolution test patterns
Opaque or transparent
Alderson ANGIOGRAPHIC HEAD PHANTOMS bridge the gap between
physical and anatomical information requirements. Molded in
tissue-equivalent material, an accurate male skull contains a 3-dimensional,
high-contrast vascular simulation to facilitate correlation of the
radiologist's subjective evaluation of angiographic image quality with
actual measurements of resolution and contrast under the same exposure
conditions.
Each ANGIOGRAPHIC HEAD PHANTOM contains a 5-step wedge. A 2-10 line pair/mm
test pattern is optional. Other patterns or test objects and custom
pathologies are available on special order.
The ANGIOGRAPHIC HEAD PHANTOM provides a "dry run" to completely check out
angiographic equipment and ensure that it is operating satisfactorily in all
significant details before subjecting patients to radiological procedures.
If the imaging system malfunctions, the phantom also plays a critically
important role in isolating and verifying correction of the problems. The
ANGIOGRAPHIC HEAD PHANTON confines the variables to components and technique
and is an invaluable service and teaching tool.
Unique RSD
soft-tissue equivalent material is used for the skin tissue and neck and is
adjusted to brain density in the cranium. This material closely duplicates
brain tissues in radio-absorptive and scatter properties. The phantom is
virtually shatterproof.
A high contrast 3-dimensional vascular pattern is placed in the median
plane. The pattern closely resembles an internal carotid arteriogram in its
early phase. The radio-density of the angiographic pattern has been adjusted
to represent a 75% contrast-media. The phantom can be used omnidirectionally.
The ANGIOGRAPHIC HEAD PHANTOM is available as either a full or half head.
The full head has the advantage of representing the full scatter properties
and subject contrast of a human head. The half-head model is well suited to
non-grid techniques. It has the advantages of lighter weight, lower cost and
smaller size, easily fitting into a briefcase.
The combination of the simulated vascular pattern, resolution chart, and
stepwedge enables the user to correlate physical parameters (such as
resolution, contrast and speed) with the subjective evaluation of the skull
markings and the vascular detail.
The ANGIOGRAPHIC HEAD PHANTOM is available in either transparent or opaque
models.
