6. Take an X-ray emission and verify that:
- There aren’t not exposed borders on the sides of the acquired area
(on the right and left)
- The dot of the ceph patient support is centred to the sensor area
Adjustments
If an adjustment is required modify the “Sens Ceph” offset according to the
following convention:
OFFSET
Effect on the image acquisition (position of
projections of dot and secondary collimator)
Sens Ceph [+]*
Move the dot/Ring the LEFT of the image;
Remove a not exposed edge on the LEFT of the
image
Sens Ceph [-]*
Move the dot/Ring the RIGHT of the image;
Remove a not exposed edge on the RIGTH of the
image
*Note: The symbols [+] and [-] mean, respectively, an increase and a decrease of
the offset value.
Offset Conversion
1 offset ≃ 2 pixel of shift of the secondary collimator position measured on the
acquired image
Furthers checks after the adjustment
If the offset has been modified perform the checks required by “Verification of
ceph function” paragraph 7.12
