Scan and Reconstruction
Concept of Scan Protocols
The scan protocols for adult and children are defined
according to body regions - Head, Neck, Shoulder,
Thorax, Abdomen, Pelvis, Spine, Upper Extremities,
Lower Extremities, Vascular, RT, Specials and
optional Cardiac, PET, SPECT and Private.
The protocols for special applications are defined in the
Application Guide “Clinical Applications” or in the
case of a Heart View examination, in the Application
Guide “Cardiac CT“.
The general concept is as follows: All protocols without
a suffix are standard spiral modes. For example,
“Sinus” means the spiral mode for the sinus.
The suffixes of the protocol name are follows:
“Routine“: for routine studies
“Seq”: for sequence studies
“Fast“: use a higher pitch for fast acquisition
“ThinSlice“: use a thinner slice collimation
“Combi“: use a thinner and a thicker slice collimation
“05s”: use the rotation time of 0.5 seconds
“ECG“: use a ECG-gated or triggered mode
“Neuro“: for neurologicial examinations with a special
mode
“Vol“: use the 3D Recon workflow
“HR“: use a thin slice width for High Resolution studies
A prefix of the protocol name is as follows:
“RT”: for radio therapy studies
The availability of scan protocols depends on the sys-
tem configuration.
“Resp”: for respiratory gated studies
The availability of scan protocols depends on the sys-
tem configuration.

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 range name in the chron-
icle can be easily changed 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.
Feed in/Feed out
The performance of the different buttons (soft but-
tons, gantry buttons, control box buttons) is standard-
ized as follows:
•inNOT loaded modes
•inloaded Biopsy mode:
1 mm
Feed In/Out = slice width x No. slice positions per scan
