5.5 Measurement method of technical factors<br />
(Paragraph for the authorized personnel)<br />
<br />
WARNING:<br />
These measurements require the removal of the HF group covers; this<br />
means to gain access to internal parts where high voltage are normally<br />
present.<br />
For the measurement of the exposure parameters with the invasive<br />
method, please follow the procedure described in paragraphs 7.2 and 7.3<br />
of the Service manual.<br />
<br />
WARNING:<br />
During the panoramic examination, the set value of kV and tube current<br />
varies according to a pre-determined curve in order to compensate the<br />
different absorption of X-ray beam due to different anatomical structures.<br />
In this way, it is possible to obtain a good uniformity of the image’s<br />
contrast. Particularly, the chosen value is lowered on the initial phase of<br />
the panoramic and increased on the scissors/canine zone, in order to<br />
compensate the effect of the cervical spine.<br />
The value displayed during the panoramic examination corresponds to<br />
the to chosen one, while the instantaneous value can be different; these<br />
effects must be considered in case of measure of the exposure factors<br />
using standard diagnostic mode (please refer to the note at page 51).<br />
Accuracy declared on the section "Technical data" is referred to the<br />
actual value of kV and/or mA. In any case, manufacturer guarantees<br />
that the accuracy of loading factors is always compliance with the<br />
international standard for safety of medical devices IEC 601-1.<br />
Particularly, in accordance with IEC 601-2-7, the maximum deviation<br />
(including the correction and instrument’s accuracy) is less than or equal<br />
to ±10 for kV, while for tube current is less than or equal to ±15%.<br />
