Introduction
Most definitions of image quality in radiology are based on characterizing the physical properties of the image chain.
However, medical diagnosis is not made by the image alone.
The perception by the observer is crucial for the result. A test of the observers perception is possible with so called
Contrast-Detail (CD) phantoms. With a CD-phantom it is possible to quantify both, detail and contrast, as observed by
the radiologist. The CDRAD 2.0 phantom can be used within the entire range of diagnostic imaging systems, such as
fluoroscopy and digital subtraction angiography.
