2–1–9 Measurement Conditions
D kVp: Connect a voltage divider such as the Machlett Dynalizer in
series with the x-ray tube and measure the voltage with an
oscilloscope,
D mAs: Use a waveform analyzer such as the Tektronic 7854, connected
in series with the x-ray tube. The oscilloscope receives a signal
proportional to the high voltage applied to the tube. The mAs
values are given by:
mAs =
ŕ
.
.
i dt
Where T1 is the time at which the high voltage reaches 75% of
its maximum value, and
T2 is the time at which the high voltage returns to 75% of the
maximum value.
