Low dose and standard dose CT scan protocols along with reconstruction parameters. All scans were acquired using a Siemens Somatom Definition AS.
| Low dose protocols Average effective dose 1.85 mSv (std. 0.58 mSv) | For children over 1 but under 6 years of age | Tube current: Eff mAs CARE Dose4D Tube potential: 120 kV Reconstruction algorithm: Kernel C30s med. smooth FR Reconstructed slice thickness: 1.0 mm | For children over 6 years of age | Tube current: 200 effective mAs Tube potential: 120 kV Reconstruction algorithm: Kernel H31f medium smooth + Reconstructed slice thickness: 1.0 mm |
| Standard dose protocols Average effective dose 3.16 mSv (std. 0.75 mSv) | For children under 6 years of age | Tube current: Eff mAs CARE Dose4D Tube potential: 120 kV Reconstruction algorithm: Kernel C30s med. smooth FR Reconstructed slice thickness: 1.0 mm | For children over 6 but under 10 years of age | Tube current: Eff mAs 286 Tube potential: 120 kV Reconstruction algorithm: Kernel H30s medium smooth Reconstructed slice thickness: 1.0 mm | For children over 10 years of age | Tube current: Eff mAs 343 Tube potential: 120 kV Reconstruction algorithm: Kernel H30s medium smooth + Reconstructed slice thickness: 1.0 mm |
