Philips Azurion - 14.6.1 Automatic Exposure Control Test; 14.6.2 Beam Limitation Check

14.6.1 Aut
omac Exposure Control Test
1 Select a pulsed uoroscopy X-ray protocol.
2 Close the shuers to apply full collimaon.
3 Perform pulsed uoroscopy twice and note the exposure parameters.
The kV value must reach the maximum programmed value (for example 110 kV) with no error
message occurring. This test also includes a test of the grid switch at the highest kV value.
14.6.2 Beam Limitaon Check
You can perform the beam limitaon check as needed If it is suspected that the beam liming device
(shuers) are malfunconing.
1 Reset the shuers.
2 Posion the tabletop horizontally and adjust it to maximum height.
3 Posion the stand with the X-ray beam perpendicular to the tabletop.
4 Posion two lead rulers crosswise on the tabletop and use tape to aach the rulers.
5 Move the detector as close as possible to the rulers.
6 Select a eld size such that the rulers span the height and width of the enre screen (see gure
below).
7 Acquire a uoroscopy image.
8 Float the tabletop to posion the center of the intersecon of the two lead rulers in the center of
the image.
9 Acquire a uoroscopy image and write down the ruler values (A1 to D1), corresponding to the
edges of the image.
10 P
osion an adequately sized lm cassee or digital lm cassee on top of the rulers.
11 Expose the lm (or digital lm) by acquiring uoroscopy.
The maximum density of the developed lm should be 0.9 ± 0.1.
12 Write down the ruler values (A2 to D2).
