Contrast sensitivity is the ability of an imaging process to produce an image of objects or tissues in the body that have relatively small physical differences or inherent contrast. The contrast that is to be imaged is in the form of some specific physical characteristic.
RADIOGRAPHIC CONTRAST â¢ It is the total amount of contrast acquired from both the anatomical part (subject) and the image receptor (film). IMAGE RECEPTOR CONTRAST â¢ It is the range of densities that the image receptor (film) is capable of recording.Mathematically this is expressed as the slope of the D Log E curve â¢ It depends on four factors: intensifying screens, film density, the D log E curve, and processing.ADIOGRAPHIC CONTRAST â¢ It is the total amount of contrast acquired from both the anatomical part (subject) and the image receptor (film).
