Radiographic Contrast/Detail Phantom

• Use for either radiographic or fluorographic systems
• Quick method for performance monitoring of the system

This phantom is used to determine the threshold contrast characteristics and to monitor performance of a radiographic or fluroscopic system. The phantom is an aluminum plate with a matrix of holes. All of the holes in a given row have a constant depth. All of the holes in a given column have a constant diameter. From this a 10 point curve is constructed by observing the shallowest depth hole that can be seen for each hole diameter.
