Comparison between Predicted and Measured X-Ray Output in Some Conventional Radiography Units ()
ABSTRACT
This study aims to investigate how accurate are TASMICS and TASMIP
models in predicting the X-ray output of some Conventional Radiology X-ray
units with high frequency generators. The X-ray output in microgray per milliampere
seconds (μGy/mAs) at 100 cm from the X-ray tube was determined
for selected high voltages and taking into account the total filtration. The
X-ray output was then measured directly with the multi-purpose detectors
(MPD), Raysafe X2. The maximum relative error between measured and predicted
values was found to be equal to 20%. The maximum relative error between
measured and predicted values obtained demonstrates the difficulty of
accurately predicting the X-ray tube output using TASMICS and TASMIP
models since they are based on fixed anode angles and different composition
of the tungsten anode.
