Resumo
In this work, tests were carried out in one X-ray system, Medicor Mövek Röntgengyara, Model NeoDiagnomax, (single –phase, full wave rectified) that operate in the range from 40 kV to 100 kV, and fixed 6 mA
in the fluoroscopic mode, with total filtration of 2.5 mmAl. It was used as reference system an invasive system
from Radcal, model Dynalyzer IIITM. The equipments tested were three non-invasive instruments, one PTW,
model DiavoltTM, and two Victoreen, model NEROTM. It was performed measurements with those equipments,
in the range from 50 kV to 100 kV, in steps of 10 kV and current of 6 mA (fixed). The quantity measured was
kVpmax. The results showed the maximum variation of 3 % for one NEROTM and 1 % for the other equipment of
the same type, and 0,3 % for DiavoltTM related to the invasive reference measurement system. The differences in
the obtained values could be caused by the different kind of equipment used in that, their manufacturer
calibration and aged.
