GAMMEX为美国ACR机构提供设计，它做为CT制造商、个人评估、影像质量、以及质量保证方面的一个主动的工程项目。该模体可应于QA评估、CT月检测试，以保证病人接受低剂量的辐射。

Product Overview
The Gammex Tissue Characterization Phantom can be used to provide 
accurate corrections for tissue inhomogeneities. The Phantom can be used
 to establish the relationship between the electron density of various 
tissues and their corresponding CT number.

The Phantom consists of a Solid Water disk approximately the size of an 
average pelvis. A matrix of 16 holes in the disk hold interchangeable 
rods made of various tissue and water simulating materials. The physical
 density (gm/cm3) and electron density relative to water of the rod 
materials are provided on a specification sheet with each phantom.

Scanning the phantom on a periodic basis provides data useful for the QA
 program of both the CT scanner and treatment planning system.
