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., 2 x
1.0
mm).
Slice width is the FWHM (full width at half maximum)
of the reconstructed image.
With the SOMATOM Spirit, you select the slice collima-
tion 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.
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 the possibilities of image
reconstruction in spiral and sequential scanning.
