Limitation of radiation dose in interventional procedures is essential to prevent radiation related complications including deterministic and stochastic effects especially in pediatrics population.  

This study compared dosage of radiation between 2D and 3D acquisitions by biplane Siemens system delivered in 24 pediatric patients. The acquisition was controlled in the same manner in each protocol to achieve good image quality with low radiation dose. There were three 3D protocols 1) factory setting (subtracted); 2) customized setting (subtracted); and 3) un-subtracted setting. As compared with 2D acquisition, all 3D protocols delivered less effective doses 68%, 15%, and 9%, respectively.
