WebContrast is the difference in density or difference in the degree of grayness between areas of the radiographic image. 7 The radiographic contrast depends on the following three factors: Subject Contrast: it refers to the difference in the intensity transmitted through the different parts of an object. For example, in an intraoral radiograph, enamel will attenuate … Web23 de abr. de 2015 · For low-contrast protocols, tube potential reduction down to the 90 kVp region affects image quality, in contrary to transition from 140 to 120 kVp. For high-contrast protocols the low...

Web-the higher the atomic #, the greater the attenuation resulting in a shorter scale of contrast. -when the differences between the atomic # of adjacent tissues is great, subject contrast … WebIntroduction: High kVp techniques, 15% or 10-kVp rules, are well-known dose reduction methods. Traditionally, the use of high tube potential (i.e. increased kVp) is associated with decreased radiographic contrast and overall image quality. Recent studies suggest contrast and image quality are not heavily reliant on kVp with digital systems. WebHigh kVp and high contrast agent concentration (110 kVp, 38% iodine) were also compared with low kVp and low contrast agent concentration (75 kVp, 15% iodine) in 62 patients … importance of market needs
