IMAGE CHARACTERISTICS🌟IMPORTANT POINTS TO REMEMBER🔹Density: It is also called photographic density. It is the term used for describing the degree of film blackening and is measured by densitometer. In diagnostic radiology, the range of optical density is 0.3–2.🔹Radiolucent areas: The white areas on the radiographic film🔹Radiopaque areas: The black areas on the radiographic film🔹Factors affecting the density of film: They consist of factors in relation with X-ray machine (kVp, milliamperage, intensity of X-ray beam, exposure time, source to film distance, filtration, grid), factors in relation with image receptor (X-ray film type,…
