Hints
• Children, who are more than 6 years old, should be
scanned with an adult protocol as the skull by this
time is fully grown.
• The UHR mode has a maximum FoV of 300 mm. It is
mandatory to position the patient in the center of
the scan FoV.
• When soft tissue is of interest, use kernel U30u for
image reconstruction.
• In order to optimize image quality versus radiation
dose, scans are provided within a maximum scan
field of 300 mm with respect to the iso-center. No
recon job with a field of view exceeding those limits
will be possible. Therefore, patient positioning has to
be performed accurately to ensure a centered loca-
tion of the skull.
