The larger the difference in thickness or density between two areas of the subject, the larger the difference in radiographic density or contrast. However, it is also possible to radiograph a particular subject and produce two radiographs having entirely different contrast levels.

As Ionizing radiation passes through the body, it is differentially absorbed by tissues of greater thickness or high atomic mass (e.g. calcium). Different portions of the body tissues ... The radiographic density is mainly the result of x-ray radiation scattering or loss of the incident radiant energy by ionization.

To investigate proper radiographic contrast and latitude based on density perception of the high-density areas of X-ray films, we studied the human characteristics of darkness perception for those areas. ... When the density of the background field was high, the larger the density difference between the background...

The less the object's radiographic density, the more X-rays reach the film, and the blacker the film appears. An object of greater radiographic density impedes more X-rays, so the film is whiter in those areas. ... Tissue and lesions visible on X-ray are categorized according to radiographic density: gas, water, fat,
