General

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.
