General
Concept
The scan protocols for adult are defined according
to body regions – Head, Neck, Shoulder, Thorax,
Abdomen, elvis, 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

Scan Set Up
Scans can be simply set up by selecting a predefined
examination protocol To repeat any mode, just click
the chronicle with the right mouse button for “repeat”.
To delete it, select “cut“. Each chronicle is rewriteable
before “load“.
Multiple ranges can be run either automatically with
“auto range“, which is denoted by a bracket connecting
the two ranges, or separately with a “pause” in between
Scan and Reconstruction
Slice Collimation and Slice Width
Slice collimation is the slice thickness resulting from
the effect of the tube-side collimator and the adaptive
detector array design In Multislice CT, the Z-coverage
per rotation is given by the product of the number of
active detector slices and the collimation
(e g 6 x 1 0 mm)
Slice width is the true thickness of the reconstructed
image
With the SOMATOM Emotion 6, you select the slice
collimation together with the slice width desired The
slice width is independent of pitch and algorithm, i e
what you select is always what you get Actually, you
do not need to care about the algorithm any more; the
software does it for you

General
If Metrorecon is not selected you will get routinely
“Real Time” reconstructed images in full image quality
The Recon icon on the chronicle will be labeled with
“RT” After the scan the Real Time displayed image series
has to be reconstructed
The following tables show you the possibilities of image
reconstruction in spiral and sequential scanning
