A CE-marked product verifies that the man-
ufacture guarantees that the product fulfills
EU:s fundamental health-, environment-
and security requirements.
The field of image is centered over the
imaging unit.
The Collimator regulates the size and shape
of the X-ray beam to accurately localize the
area of interest on the patient, while reduc-
ing overall patient irradiation exposure.
Either a physical collision with an obstacle
or the node cannot reach its end position.

Dose Area Product.
DAP (Dose Area Product) is a quantity used
in assessing the radiation risk from diagnos-
tic X-ray examinations and is presented in
dGycm².
Defined as the absorbed dose multiplied by
the area irradiated. The DAP is independent
of distance from source.
The DAP meter is placed next to the colli-
mator and measures the amount of X-ray
radiation that leaves the collimator.
An X-ray system designed for irradiation of
any part of the human body for the purpose
of diagnosis or visualization.
Electrical component that leads voltage and
current in one direction.
See supplier.
Deviation Index. According to Standard IEC
62494-1: "Deviation Index (DI) is a number
quantifying the deviation of the actual expo-
sure index from a target exposure index."
Digital Imaging and Communications in
Medicine (DICOM).
An industry standard specifications for inter-
connection of medical imaging equipment.
