This fact may cause considerable difficulty in the statistical analysis of the experimental results, and based in this concept, the present method was developed, to compare the diagnostic quality by means of the radiographic density and contrast using a single mathematics transformation of the original data of densities.
Analysis was performed by means of an internal supplied histogram program that measures each pixel's radiographic density over a defined area.
The relative number of x-ray photons necessary to cause film darkening is characterized by the term "speed." A screen or film classified as "fast" requires less radiation dose to produce a specific radiographic density.[5] The evaluation of speed vs noise for each type of examination influences radiation dose and image quality.
