The pediatric scan protocols are defined under the folder “Children”. The protocols for special applications are defined under “Special”. The general concept is as follows: “Fast”: uses 1.5 mm slice collimation and a higher pitch for fast acquisition for CT Angios or trauma cases. “Routine”: uses either 0.75 mm or 1.5 mm slice collimation depending on the region of interest for routine studies. “ThinSlice”: uses 0.75 mm slice collimation for thin slice studies. “Combi”: uses 0.75 mm as slice collimation and reconstruct images as both thinner slice width for HiRes or CTA and thicker slice width for soft tissue studies. “Seq”: stands for Sequence. E. g. “HeadSeq” means the sequence mode for the head; “Spi” stands for “Spiral”. E. g. “HeadSpi” means the spiral mode for the head. 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”, or separately with a “pause” in between. 8 General Scan and Reconstruction Slice Collimation and Slice Width Slice collimation is the slice thickness collimated by the tube collimator, which determines the Z-coverage per rotation. In Multislice CT, this is divided ...
