DR detector and X-ray tube head alignment
The tube head display 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.
1.
The relative angle between the DR detector and the horizontal surface.
2.
The rotation of the DR detector around the vertical axis. This angle is not
measured and 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.
Depending on the orientation, the angle may be displayed as a negative
number. The number sign is ignored for comparing the angles.
The availability of the alignment feature depends on the DR detector model
and on the product license.
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.
