Update
An image that has high contrast will have Few shades of gray
Coherent scattering event may also be called Classic scattering
During a serious of portal cheat x-rays, the technologist fails to adjust the kvp for an especially
large patient. This is likely to result in quantum mottle
Bremsstrahlung X-ray photons are produced by electrons interactions with which aspect of the
tungsten atom? Positive charge of the atomic nucleus
An image is taken using 10mAs with 5:1 grid. What mAs is needed to maintain receptor
exposure when switching to a 16:1 grid 30mAs
Cathode Negative electrode
Anode Positive electrode
anode heel effect Uneven distribution of radiation intensity in the x-ray beam.
As the distance of the beam is doubled what happens to the quantity of the photons reaching the
image receptor The number of photons reduce to 1/4
kVp quality
mAs Quantity
