General
Concept
The scan protocols for adult are defined according
to body regions – Head, Neck, Shoulder, Thorax,
Abdomen, Pelvis, Spine, Extremities.
The pediatric scan protocols are defined under the
folder “Children“.
The protocols for special applications are defined
under “Special“ (please refer to the Application Guide
for Special applications).
The general concept is as follows:
All not specially marked protocols are standard spiral
modes. E. g. “Head” means the spiral mode for the head.
“Fast“: uses 2.0 or 3.0 mm slice collimation and
a higher pitch for fast acquisition for CT Angios or
trauma cases.
“Routine“: uses either 1.0 mm or 2.0 mm slice colli-
mation depending on the region of interest for routine
studies.
“ThinSlice“: uses 1.0 mm slice collimation for thin
slice studies.
“HR“: uses 0.5 mm (optional) or 1.0 mm slice colli-
mation and rotation time of 1.0 s for High-resolution
studies.
“Combi“: uses 1.0 mm as slice collimation and by
default, has 2 reconstruction jobs: one thin slice width
for HiRes or CTA, and one thicker slice width for soft
tissue studies.
“Seq“: stands for Sequence. E. g. “HeadSeq“ means
the sequence mode for the head.
The existence of scan protocols depend on the system
configuration. Protocols with the 0.6 sec. rotation time
are only available on systems configured with the Power
Package, also 0.5 mm slice collimation is available only
on systems with High Resolution option.
