Effect of mAs and kVp on resolution and on image contrast

Web6 de mar. de 2016 · Kilovoltage peak (kVp), milliamperage (mA), and exposure time all are factors that the radiographer selects on the control panel to produce a quality image. The radiographer also needs to be aware of the amount of heat that is produced during x-ray production because excessive heat can damage the tube. X-Ray Production Weboperating voltage (in kVp). A dental x-ray machine operating at a peak voltage of 70,000 volts (70 kVp) for example, apples to a fluctuating voltage of as much as 70 kVp across the tube. This tube therefore produces x-ray photons with energies ranging to a maximum of 70,000 keV (70 keV). The reasons for this continuous spectrum are as follow: 1. pool wärmepumpe evolution

WebA choice of low kVp results in short-scale contrast having two steps – black and white. Choosing a high kVp creates films with a long-scale contrast of five steps – black, dark gray, medium gray, light gray, white. Optimum kVp for any body part produces an intermediate-scale contrast of four steps – black, dark gray, light gray, white.2 Webmilliamperage-seconds(mAs), kilovoltage(kVp), source–image receptor distance(SID), and filtration.

WebKilovoltage potential (kVp) is the highest potential voltage achieved at any given kV setting. Higher kV settings produce more penetrating beams in which a higher percentage of the x-rays produced penetrate the subject being radiographed. There is also a decrease in the percentage difference in absorption between tissue types.
