Breast Phantom

|
|
The Gammex 169 “Rachel” Anthropomorphic Breast Phantom is a unique test instrument that produces an image with the
contrast range and details found on a clinical mammogram. This phantom may be used for evaluation of effects of changing
mammographic imaging parameters such as machines, machine settings, film/screen combinations, and digital image
processing. The use of a simulated mammogram complements the usual test objects by providing an overall visual
comparison.
The active portions of the phantom consist of a base and an imaging target. The base is constructed usingBR-12 (breast
equivalent material) formed to simulate typical breast thickness variations. Tissue detail is provided using a test target
derived from a clinical mammogram. The target itself is a digitally processed film image of the mammogram that was then
enhanced with mercury. These elements are contained within a protective case. This case is designed to facilitate
reproducible positioning of the phantom in the mammographic machine. |
