What does the term 'dynamic range' refer to in digital DXR imaging?

Dynamic range in digital DXR (Digital X-ray Radiography) imaging specifically refers to the range of exposure levels that a detector can accurately capture. It indicates the ability of the imaging system to respond to different levels of radiation intensity and to display the corresponding variations in image brightness and contrast. A high dynamic range allows for better differentiation of tissues and structures in an image, which is crucial for accurate diagnosis.

In practice, this means that a detector with an extensive dynamic range can produce images that retain detail in both very light and very dark areas, which is essential in radiographic imaging where various tissues have different densities. This contrasts with other concepts such as storage capacity, variety of techniques, or processing speed, which do not pertain to the sensitivity and accuracy of the detector in capturing exposure levels. The dynamic range is a critical aspect that enhances the overall quality and usability of DXR imaging in clinical settings.
