Abstract
An x-ray system ( ) include a digital detector ( ) that defines two regions: a first region ( ) suitable for generating data useful for creating a patient x-ray image and a second region ( ) less suitable for generating such data than the first region. A source ( ) transmits x-rays through a phantom ( ) located between the source and the second region ( ) so that the detector ( ) generates test data in the second region. A processor ( ) measures at least one parameter in response to the test data and stores a value of the parameter at one point of time. The processor compares the first value with a second value of the one parameter generated at a later second point in time. The processor also generates a result signal representing the results of the comparison.
