Lmrt Test / X-Ray Production Questions And
Answers|Latest Update
The rate of current flow across the x-ray tube is measured in: mA or milliamperage
doubling the mAs increases patient dose. doubles photons in the xray beam; increases
density
unit that describes total QUANTITY of xray exposure: mAs
mA x time = mAs 200 ma, 0.2 sec, 70 kvp @ 40 in SID creates a value of mAs = 40
device to remove long wavelength radiation from primary xray beam: filtration
xray equipment capable of producing 70kvp or more is required to have filtration of at least:
2.5 mm Al equiv
purpose of rotating anode of xray tube: increase the heat capacity of the anode
image sharpness is determined by Size of the effective focal spot.
ABOVE 70 kVp, what percentage of photons is created by the bremsstrahlung process?
85%
The amount of detail present in any image is known as ______ resolution. spatial
Roentgen discovered xrays while working with: crooks tube
electron cloud surrounding the filament of cathode is called: a space charge
