So the subject contrast is said to be higher in the chest than in the abdomen. Material Properties. Kimberly P. Aluminum needed to reduce x-ray beams intensity by half. Electrons striking with more energy results in X-rays with more penetrating power. This article needs additional citations for verification. Study these flashcards. Chelsey H.
In x-ray equipment, kilovoltage controls 1.
Video: Kilovoltage controls the activities ⚡PART 3 - RADIOGRAPHIC DENSITY with kVp and mAs and 15% kVp rule.

3. penetrating power of radiation. 4. amount of radiation produced. All of the above.
The high-voltage potential is measured in kilovolts, and this is controlled with the voltage or kilovoltage control on the control console. An increase in the. Review radiographer quality control activities and reports; evaluate retake activity; Kilovoltage controls the wavelength of the x-ray photons generated and.
Hidden categories: Articles needing additional references from December All articles needing additional references.
Alternately, small, lightweight components may only require a system capable of producing only a few tens of kilovolts. Electrons striking with more energy results in X-rays with more penetrating power.
Increasing mAs causes more photons radiation of the particular kVp energy, to be produced. In dental imaging, the quantity of radiation produced is controlled by:. Constant potential generators rectify the AC wall current and supply the tube with DC current.
Controlled areas, –, Control panels kilovoltage radiotherapy, high-activity bodies, Criteria of acceptability, megavoltage radiotherapy. In dental radiography, the quality of the x-ray beam is controlled by: kilovoltage peak milliamperage exposure time source-to-film distance.
Peak kilovoltage kVp refers to the maximum high voltage applied across an X-ray tube during the creation of x-rays within it. Some systems have external vacuum pumps to remove any oxygen that may have leaked into the tube.
Each body part contains a certain type of cellular composition which requires an x-ray beam with a certain kVp to penetrate it. However, scattered x-rays also contribute to increased film density: the higher the kVp of the beam, the more scatter will be produced. The high-voltage potential is measured in kilovolts, and this is controlled with the voltage or kilovoltage control on the control console.
