Measurement Basis for Technique Factors
kVp - The peak value of high voltage generator output in the interval after a 20 mS delay period to
the end of the exposure.
mA - The time average of the current flow into the high voltage cable/X-ray tube assembly,
beginning at the point where kVp crosses the 35 kVp level.
Time - Measurement of exposure time begins when the kVp crosses the 35 kVp level ( 80% of kVp
selected).
mAs - The time integral of mA as defined above.
