The article’s purpose was to present dose optimization data using digital radiography in pelvis simulators representing children aged 1 and 5 years, mainly due to the lack of similar studies that consider variations in age and size in the pediatric pelvis image.

They included assessments of image quality and radiation dose in phantoms, using variations in acquisition factors (kVp, mAs, source-detector distance [SDD], and filtration) to acquire X-ray images of the AP pelvis.

The quality of the perceptual image was assessed using a method of evaluating relative and absolute visual gradation. The radiation doses were measured by placing a dosimeter at the point of radiographic centralization on each phantom’s surface. And the statistical analyzes to determine the optimized parameters included the analysis of the main effects.

The conclusion was that the study provided a method to investigate the combined effect of various acquisition parameters on image quality and radiation dose for children. To access the full article, click here.
