By reducing the FoV for 3D X-ray imaging on children or adolescents, you are reducing the exposed area, and this reduces the dose received by the patient.
For a recommendation on the FoV to be selected for children/adolescents, see the table below:
Standard FoV |
Recommended FoV for Children/Adolescents |
5x5 |
4x4 |
10x5 |
8x5 |
10x10 |
8x9 |
12x5 |
10x5 |
12x10 |
10x10 |
