Hints in General
1.Topograms: 256 mm lateral topograms are defined
for the head modes, and 512 mm AP topograms are
defined for the body modes. Please keep in mind that
the children’s size can be dramatically different. You
should press the “Hold Measurement“ button when-
ever the range shown on the real time growing topo-
gram is long enough, in order to avoid unnecessary
radiation.
In a consistent effort to reduce the total dose of an
examination, all topograms of the pediatric protocols
are defined at 80 kV with minimum current (50 mA).
2. Gantry tilt is available for sequence scanning, not
for spiral scanning.
3.For all head studies, it is very important for image
quality purposes to position the patient in the center of
the scan field. Use the lateral laser beam to make sure
that the patient is positioned in the center.
4.Warm surroundings and dimmed lighting are helpful
to make children more cooperative.
