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.
