Radiograph Density and Contrast
- The difference in density between areas in the radiograph is determined by the attenuation coefficient of the various tissues.
- The term contrast is used to describe the visibility of diagnostically important detail in the radiograph.
- Subject contrast refers to the difference in x-ray intensity transmitted through one part of the subject compared to another part.
- The attenuation of the x-ray beam by the patient results in radiographic density.
- Subject contrast depends on the difference in absorption of x-rays by different tissues.
