Gammex’s new 621 Lung CT Reference Phantom is a simple to use device that will provide a CT number in the range of common lung disorders. It consists of an acrylic shell that houses four reference sections. The material in each section has a different density and a correspondingly different CT number.

When scanned, the Gammex 621 Lung CT Reference Phantom will yield a CT number unique to that section. The Lung CT Reference Phantom is intended to be used as a CT number reference that is a constant so that any systematic errors due to scanner parameters drifting or the use of different scanners on the same patient during a longitudinal study may be detected and corrected.

The phantom shape and material is such that it will not cause artifact in the image so it is possible to place the phantom on top of the supine patient during the exam if so desired.
