7.6 Attenuation Equivalent
WARNING!
The PRS 500 E can be supplied with different options for the X-ray cassette
holders. The device attenuation factor must be determined during the
acceptance test. The variable components such as the X-ray tube, collimator,
anti-scatter grid, measuring chamber, dose area product meter, tabletop, etc.
change the factor individually. The attenuation values of the components can
be taken from the corresponding accompanying papers. The determination of
the device attenuation factor must be carried out according to the specialist
regulations. If the prescribed values cannot be met, this must be reported to
PROTEC immediately.
If additional components (positioning aids, etc.) are placed in the beam path,
this will have a negative effect on the quality of the X-ray exposure.
The tabletop is defined as an applied part.
The aluminium attenuation equivalent of the tabletop is typically 0.7 mm Al and <0.8 mm Al for carbon;
0.85 mm Al for composite material according to EN 60601-1-3 at 100 kV and a first half-value layer
thickness of 3.6 mm Al and typically 0.6 mm Al and <0.8 mm Al according to 21CFR § 1020.30 (m) at
100 kV and a first half-value layer thickness of 3.6 mm Al.
The Bucky cover of the image receptor stand is defined as an applied part.
The aluminium attenuation equivalent of the cover is typically 0.4 mm Al and <0.5 mm Al according to
EN 60601-1-3 at 100kV and a first half-value layer thickness of 3.6 mm Al.
7.6.1 Protection Art and Protection Class
The PRS 500 E corresponds to protection class 1 and contains applied parts type B (according to EN
60601-1).
7.7 Automatic Cut-off Dose
7.7.1 Analogue System
The automatic cut-off dose is 2.5 µGy.
7.7.2 Digital System
The automatic cut-off dose depends on the detector.
For RAPIXX systems see instructions for use of the corresponding RAPIXX system (Chapter 3.2; 3.3)
