- IR/detector manufactures specify an expected range of x-rays exposure that will produce a good-quality image
- A quality radiographic image accurately represents the anatomic area of interest
- Brightness, contrast, spatial resolution, and distortion are all factors
- X-ray tubes that have excessive or insufficient filtration may begin to affect image quality

The radiograph must exhibit differences in the brightness levels or densities (image contrast) in order to differentiate among the anatomic tissues.
