X-ray detector image quality test techniques |
摘要 |
An x-ray system (10) include a digital detector (400) that defines two regions: a first region (404) suitable for generating data useful for creating a patient x-ray image and a second region (406) less suitable for generating such data than the first region. A source (20) transmits x-rays through a phantom (420) located between the source and the second region (406) so that the detector (400) generates test data in the second region. A processor (302) 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.
