Medical diagnosis is not made by image alone; observer perception greatly affects the result. With the CDRAD Phantom from Nuclear Associates, it is possible to quantify both detail and contrast as observed by the radiologist. The CDRAD Phantom also is an excellent tool for evaluating the imaging characteristics of digital radiographic systems, including stimulable phosphor computed-radiography systems and teleradiography systems.
The CDRAD Phantom (Model 07-652) consists of a Plexiglas tablet with cylindrical holes of exact diameter and depth (tolerances: 0.02 mm). To evaluate the Phantom image, the observer indicates the location of the second spot in each square. Correct indication proves that a contrast is really seen.
