7.6 Attenuation Equivalent
WARNING!
The radiographic system PRS 500 E can be delivered with different options on
the Grid Entity/Bucky.
The attenuation factor must be determined at the final inspection at the
customer. The variables like X-ray tube, Collimator etc. have influence to the
factor. The attenuation value of the components can be read out of the
accompanying documents of the component. The attenuation value has to be
determined at the technical specifications. If the limits can’t be kept please
inform PROTEC immediately. If additional accessories are use it has a negative
influence to the quality of the X-ray image.
The table top is defined as application part.
The aluminium attenuation equivalent of the table top is typically 0, 7 < 0, 8 Al mm for carbon / 0, 85
mm Al for composite fibre, according to EN 60601-1-3. Tested at 100 kV with a first half-value layer
thickness (HVLT) of 3, 7 mm Al and typically 0, 6 mm Al und <0,8mm Al according 21CFR § 1020-30 (n)
with 100 kV and a first half-value layer thickness (HVLT) of 2,7mm Al.
The cover vertical X-ray system image receptor stand is defined as application part.
The aluminium attenuation equivalent of the cover vertical X-ray system image receptor stand is
typically 0,4 and < 0,5 Al mm according to EN 60601-1-3. Tested at 100 kV with a first half-value layer
thickness (HVLT) of 3,7 mm Al.
7.6.1 Protection Art and Protection Class
The PRS 500 E is consistent with a protection class 1 device and contains applicable parts Type B
(according to EN 60601-1).Environmental conditions.
7.7 Automatic cutoff dose
7.7.1 Analogue System
The automatic cutoff dose is 2.5 µGy.
7.7.2 Digital System
The automatic cutoff dose depends on the detector.
