- 1 The more sensitive the film-screen system is to radiation faster the speed faster the speed grerater density Film-screen relative speeds range 50 RS to as high as 800 RS larger field size (decreasing collimation) increases density thicker the part decreases density for every change in part thickness of 4 to 5 cm adjust the mAs by a factor of 2

- The clarity and sharpness of the image is a true representation of the subject. These features make up the four elements of radiographic quality: density, contrast, detail, and distortion. Radiographic or Optical Density The overall blackness of the image is referred to as the radiographic density or optical density (OD).

- The concept of radiographic quality considers the factors that determine the success of this aim. The quality of a radiograph depends on two photographic properties and two geometric properties: density and contrast (the photographic properties); definition and distortion (the geometric properties).

- Images with gross over- or underexposure, gross unsharpness, and gross departures from proper radiographic contrast should all be classified “U/R” (see appended reprint from the Federal Register for radiographic quality standards). If the technical quality is not grade 1, an indication of the technical defect(s) must be made.

- Thicker structure being imaged. Greater difference between the attenuation of the two objects. Subject contrast. In the diagram tissue A absorbs 50% of the radiation incident upon it, B absorbs 90%. If there are 1000 photons for every element of the image then 500 photons will emerge from A and 100 from B (a ratio of 5:1).
