This study examines a novel protocol implemented in 2016 at Região Autónoma da Madeira, a Portuguese island. It involves the mobilization of experienced neuro...
Assessment of Patient Dose Reduction by Bismuth Shielding in CT Using Measureme...
Mendes, M; Costa, F; Figueira, C; Madeira, P; Teles, P; Vaz, PThis work reports on the use of two different Monte Carlo codes (GEANT4 and MCNPX) for assessing the dose reduction using bismuth shields in computer tomography (CT) procedures in order to protect radiosensitive organs such as eye lens, thyroid and breast. Measurements were performed using head and body PMMA phantoms and an ionisation chamber placed in five different positions of the phantom. Simulations were p...
