Implication

Monte Carlo simulations reveal that specific projections and copper filtration effectively reduce radiation exposure in pediatric patients with scoliosis.

Key Points

This research aims to evaluate how different projection techniques and copper filtration influence radiation doses in pediatric imaging.
Monte Carlo simulations were conducted using a particle transport code to model full-spine radiography.
Age-specific female phantoms (5, 10, and 15 years) were used to assess organ doses under various imaging conditions.
The impact of anteroposterior and posteroanterior projections was analyzed, both with and without copper filtration.
PA projection significantly reduced radiation doses to radiosensitive organs, achieving reductions up to 93% for the breast.
Copper filtration contributed an additional 15-19% dose reduction in AP and 5-6% in PA projections.
Increased doses were noted in deeper organs such as the kidneys and active bone marrow.
