One of the main criteria that must be held in Total Body Irradiation (TBI) is the uniformity of dose in the body. In TBI procedures the certification that the prescribed doses are absorbed in organs is made with dosimeters positioned on the patient s

Due to the difficulty in implementing invasive techniques for calculations of dose for some exposure scenarios, computational simulators have been created to represent as realistically as possible the structures of the human body and through radiatio

We developed exposure scenarios of pediatric interventional cardiology using a newborn hybrid phantom and the radiation transport code MCNPX. Six angiographic projections (AP, PA, LAO45, RAO45, LAO90 and RAO90) were simulated considering three X-ray

The conversion coefficients (CCs) relate protection quantities, mean absorbed dose (DT) and effective dose (E), with physical radiation field quantities, such as fluence (Φ). The calculation of CCs through Monte Carlo simulations is useful for estim
