Introduction
1.1 Product Description
The Contrast Detail Phantom for Mammography is designed to provide a means of quantitatively testing
and monitoring the total performance of an entire mammographic imaging chain. Its small size, as well as
the number and distribution of holes simulating embedded objects, make this phantom particularly useful
in evaluating digital spot mammography systems. With 49 holes generating subtle contrast variations, the
phantom makes it possible to detect small changes in overall system performance.
Included with your wise purchase is a tube of grease. The phantom can be taken apart and a liberal
application of grease applied to the inner (holed) surfaces, to decrease the contrast from air and eliminate
all air artifacts. After putting the phantom back together, simply wipe the excess grease from the edges.
