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.
• When bone structure is of interest, use kernel C60s
for image reconstruction.
• An advanced algorithm allow for improved head
image quality, without any additional post-process-
ing.
• 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.
