Accurate testing of all CT scanner parameters is a crucial part of a good QC program. The Head/Body CT Phantom is designed for a complete CT quality assurance program, including daily quality control tests and periodic, comprehensive QC testing to meet the requirements of the FDA.

The Head/Body Phantom consists of a head module which is a tapered disc of Solid Water® phantom material. To test a CT scanner in the head scanning mode, a ring of compact bone is mounted on the head module; for testing in the body scanning mode, a body annulus is mounted on the head module. The head module has 5 tapered cavities which accept tapered test inserts and the body annulus ring has 4 cavities, providing for a total of 9 test positions. Standard test inserts make basic QC tests possible, while the optional test inserts allow for more sophisticated tests that may be useful for physicists and engineers. These inserts are designed for maximum flexibility with a minimum of time, effort, and cost.

Reproducibility and consistency between tests can be achieved with the Head/Body CT Phantom because of its Solid Water construction. This eliminates the problems and inconvenience found with water-fillable phantoms. And because of its design, custom tests or new developments can easily be accommodated into the Head/Body CT Phantom. A carrying case in included.
