Children

Hints

• Children, who are more than 6 years old, should be

scanned with an adult protocol.

• The second recon job is deﬁned with kernel H60s

and with an overlap for visualizing bone structures

with MPR.

• If the study is focused on bone structure only, the

mAs can be reduced to 20 for all age groups.

• In order to optimize image quality versus radiation

dose, scans are provided within a maximum scan ﬁeld

of 300 mm with respect to the iso-center. No recon

job with a ﬁeld of view exceeding those limits will be

possible. Therefore, patient positioning has to be

performed accurately to ensure a centered location

of the skull.

• To work without CARE Dose 4D use for children

< 3 years 40 mAs

3-6 years 60 mAs.
