NOTE:
During the Panoramic, the value of the exposure parameters varies
according to a fixed curve, to compensate the variations in absorption by
the patient's tissues. In this way, it is possible to obtain a good
uniformity of the image contrast. In particular, the chosen value of the
kV is lowered in the initial and end sections of the panoramic and
increased on the incisors/canine zone.
The tube current varies according to the kV, also if the set value is
slightly increased on the initial/end sections. These variations have the
effect of compensating the higher absorption of X-ray in the zone of the
spinal column. As an example, the variation of the parameters follows the
curve below:
Set value
Actual value mA
Actual value kV
The values displayed during the panoramic examination correspond to
the ones chosen by the user, while the real value in the various positions
of the examination cycle can be different; in any case, the system
guarantees that the accuracy of the exposure parameters is always
within the limits set by the international standards for the safety of
medical devices, IEC 60601-1. In particular, in accordance with
IEC 60601-2-7, the maximum deviation (including the correction
according to the above curve and instrumental doubt) is within
±
10% for
the kV, while for the tube current it is within
±
15%.
