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 system configuration.
“Resp”: for respiratory gated studies
The availability of scan protocols depends on the system configuration.
18
Scan and Reconstruction
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 chronicle 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.
The performance of the different buttons (soft buttons, gantry buttons, control box buttons) is standardized as follows:
•in NOT loaded modes 1 mm
•in loaded Biopsy mode:
Feed In/Out = slice width x No. slice positions per scan 2

Scan and Reconstruction
This is an incremental, slice-by-slice imaging mode in which there is no table movement during data acquisition. A minimum interscan delay in between each acquisition is required to move the table to the next slice position.
Spiral scanning is a continuous volume imaging mode. The data acquisition and table movements are performed simultaneously for the entire scan duration. There is no inter-scan delay and a typical range can be acquired in a single breath hold.
Each acquisition provides a complete volume data set, from which images with overlapping can be reconstructed at any arbitrary slice position. Unlike the sequence mode, spiral scanning does not require additional radiation to obtain overlapping slices.
21
Scan and Reconstruction
The data is usually acquired during a full 360° rotation
– this is a Full scan. Data acquisition not using a full 360° rotation is called a “Quick scan”. Quick scans are employed to reduce motion artifacts and improve the temporal resolution.
Multiple continuous rotations at the same table position are performed for data acquisition. Normally, it is applied for fast dynamic contrast studies, such as syngo Neuro Perfusion CT.
Dynamic serial scanning mode without table feed. Dynamic serio can still be used for dynamic evaluation such as Test Bolus. The image order can be defined on the Recon subtask card.

Acquisition, 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 1.0mm for the SOMATOM Emotion 6-slice configuration or 16 x 0.6mm for the SOMATOM Emotion 16slice configuration ).
Slice width is the FWHM (full width at half maximum) of the reconstructed image.
With the SOMATOM Emotion 6/16-slice configuration, you select the slice collimation together with the slice width desired. The slice width is independent of pitch, 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.
If Metrorecon/Fastrecon is not selected you will routinely get “Real Time” images. The Recon icon on the chronicle will be labeled with “RT”. After the scan the Real Time displayed image series has to be reconstructed.
In some cases – this depends also on Scan pitch and Reconstruction increment – the Recon icon on the chronicle will be labeled with “RT”. This indicates the Real Time display of images during scanning. The Real Time displayed image series has to be reconstructed after completion of spiral.
The Acq (Acquisition) is displayed on the Examination task card. The Acquisition is simply "number of slices acquired per rotation" x "width of one slice".

Scan and Reconstruction
The increment is the distance between the reconstructed images in Z direction. When the chosen increment is smaller than the slice thickness, the images are created with an overlap. This technique is useful for reducing partial volume effect, giving you better detail of the anatomy and high quality 2D and 3D postprocessing.
The increment can be freely adapted from 0.1 - 10 mm.
Pitch = feed per rotation z-coverage
z-coverage = detector rows x collimated slice width
Feed/Rotation = table movement per rotation
The Pitch Factor can be freely adapted from 0.45 – 2.0, in Cardio, there is a fixed pitch down to 0.1.
With the SOMATOM Emotion 6/16-slice configuration, you select the slice collimation together with the slice width desired.
The slice width is independent of pitch, i.e. what you select is always what you get. Actually, you do not need to be concerned about the algorithm any more; the software does it for you.
Pitch values with a step width of 0.05 can be selected for all modes.
We recommend to use a Pitch Factor of 0.45 for MPR reconstructions.

There are 4 different types of kernels: “H“ stands for Head, “B“ stands for Body, “C“ stands for ChildHead and ”S” stands for Special Application, e.g. syngo Osteo CT.
The image sharpness is defined by the numbers – the higher the number, the sharper the image; the lower the number, the smoother the image.
