Scan and Reconstruction

Positioning
In order to optimize image quality versus radiation
dose, scans in body regions “Head” and “AngioHead”
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. There-
fore, patient positioning has to be performed accu-
rately to ensure a centered location of the skull.

For trauma examinations of the head we provide two
protocols, to be found in the specials folder:
– HeadTrauma
– HeadTraumaSeq.
The scan protocols enable you to utilize the full 50 cm
FoV, resulting in easier patient positioning for trauma
examinations and to ensure the highest performance,
the dedicated PFO head filter is not used.
