Cross-sectional experimental study evaluates reduced radiation exposure in pediatric radiography using aluminum and copper filtration, indicating practical optimization strategies.

Key Points

This study aims to quantify the reduction of radiation dose in pediatric chest radiography using aluminum and copper beam filtration.
Cross-sectional experimental study using a polymethyl methacrylate phantom to simulate pediatric chest imaging.
Imaging conducted at 70 kVp with automatic exposure control under four filtration conditions: no filtration, 1.0 mm aluminum, 0.1 mm copper, 0.2 mm copper.
Evaluation of dose area product (DAP) with a calibrated meter after seven repeated exposures per condition, with statistical analysis via one-way ANOVA.
Highest mean DAP observed without filtration at 0.628 ± 0.005 Gy·cm2.
1.0 mm aluminum filtration reduced DAP by 27.2% (0.457 ± 0.008 Gy·cm2).
0.2 mm copper filtration produced the greatest reduction of 54.9% (0.283 ± 0.006 Gy·cm2), with statistically significant differences (p < 0.05).
