- 1kVKilovoltage
controls the energy (penetrating power) of the x-ray beam - 2mAMilliamperage
controls the quality or number of x-rays produced - 3msExposure time
controls the duration of the exposure
usually in milliseconds - 4CONTRASTthe difference in density between adjacent areas of a radiographic image
- 5DENSITYthe amount of "blackness" on the processed radiograph
- 6What is the primary controlling factor of DENSITY?mAs
controls the quantity of x-rays emitted from the x-ray tube AND the duration of exposure - 7What's the primary controlling factor of CONTRAST?kV
higher kV = lower contrast
lower kV = higher contrast - 8Annode Heel EffectThe patient should be positioned so the thicker portion of the body (part) is at the CATHODE end of the x-ray tube
The thinner part of the body (part) should be positioned under the ANODE - 9What happens to your image if the CR is not centered on the grid?The image will be laterally off center
