Hints
• An automatic bone correction allows for improved
head image quality, without any additional post-pro
-
cessing.
• 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.
