Description

The basic inspection techniques of X-ray digital radiography and computed tomography use some kind of X-ray detector in the form of an array or a single point. Most of the detectors available today have high performance characteristics in certain areas but not all. For example, a collimated germanium detector has good energy sensitivity and can provide high spatial resolution. But it has the disadvantages of being very slow and having to be operated at liquid nitrogen temperatures. An array detector such as an image intensifier viewed by a CCD camera has the advantage of being very fast, but it has poor dynamic range compared to a germanium detector.
