DR detector and X-ray tube head alignment
The examination overview screen can show a readout of the tilting angle of
the DR detector and of the X-ray tube head.
The relative angle between the DR detector and the horizon-
tal surface.
The relative angle between the X-ray tube and the vertical ax-
is.
When both angles differ by less than one degree, they're displayed in green.
The exposure is perpendicular if both angles are displayed in green and the
tilting axes of the DR detector and of the X-ray tube head are parallell. The
alignment of the tilting axes must be visually verified by the user.
If the angle is very small (smaller than 3 degrees), it is hard to visually verify
the alignment of the tilting axes. Use the light field of the collimator to verify
the alignment of the X-ray tube head to the DR detector.
CAUTION:
The alignment readout may not be available, e.g. if the position
of the detector is not stable due to movement of the patient. A
skilled operator can do the alignment visually and using both
goniometers on the X-ray tube head.
WARNING:
There can be a delay on the readout of the tilting angle
compared to the actual value. Confirm visually that the position
of the X-ray tube head and the DR detector is stable.
