The special kernels are mostly used for ”physical” mea-
surements with phantoms, e.g., for adjustment proce-
dures (S80s), for constancy and acceptance tests 
(S80s, U90s), or for specification purposes (U90s). For 
special patient protocols, S80s and U90s are chosen, 
e.g., for Osteo (S80s) and for high resolution bone 
studies (U90s). 

Patient positioning:

• Set the table height at 125. The gantry tilt will be 

available from –22° to +22°.

• Patients should be positioned straight on the table.

 

Support the knees to compensate for lordosis.

• The calibration phantom should be positioned 

directly below the target region.

 

Put the Gel-pad between the calibration phantom 
and the patient to exclude air pockets.

Scanning:

• For obese patients increase the mAs value to 120.
• Typically, one scan each is performed at L1, L2 and 

L3 levels. Use image comments L1, L2, L3, L4, L5, or 
T12 prior to scanning of the respective vertebrae, 
these comments will be used for syngo Osteo CT 
evaluation results (no blanks or other deviations are 
allowed, e.g., use “L4“ instead of “L 4“, or “T12“ 
instead of “TH12“).

• Before ending the examination, you can drag & drop 

the recon jobs from the chronicle to the topogram 
segment to get the Topographics, i.e. the cut lines 
for each vertebra on the topogram.
