Optical density def
WebDefinition. As mentioned previously, radiographic definition is the abruptness of change from one density to another. Geometric factors of the equipment and the radiographic setup, and film and screen factors both have an effect on definition. Geometric factors include the size of the area of origin of the radiation, the source-to-detector (film) distance, the … WebOptical Density (OD), the log base 10 of the fraction of light transmitted through an unexposed film to the light transmitted after exposure. I0 is the light collected without film. I is the light collected after passing through film. T is the transmittance; the ratio of the light transmitted through film to the light transmitted without film.

WebOptical Density. This value indicates light transmittance and is used for white and black type films. The higher the optical density, the lower the transmittance. When the transmittance is 100%, the optical density is 0. Measured using an optical densitometer. Measured using an optical densitometer.

WebDefinition: The optical density of a material is a logarithmic ratio of the falling radiation to the transmitted radiation through a material. It is also referred as a fraction of absorbed radiation at a particular wavelength. WebJul 26, 2024 · Radiographic or Optical Density. The overall blackness of the image is referred to as the radiographic density or optical density (OD). When the radiographic density is optimum, the image is both dark enough and light enough for you to see the anatomic details clearly on the viewbox. In conventional film / screen system, density is controlled ...
WebMay 4, 2012 · Let me provide an operational definition of optical density: Write the number 1 and follow it with as many zeroes as the optical density. The number you get is the optical attenuation. Example: after passing a filter of optical density 6, the outgoing light has been attenuated one million times. Hope this is clear enough.
