Artigo IPEN-doc 23121 Attenuation coefficient determination of printed ABS and PLA samples in diagnostic radiology standard beams2016 - VENEZIANI, G.R.; CORREA, E.L.; POTIENS, M.P.A.; CAMPOS, L.L.IAEA code of practice TRS-457 states that standard phantoms should offer the same primary attenuation and scatter production as relevant body section of a representative patient. Material cost, availability and dimensional stability must also be considered. The goal of this study is to determine the attenuation coefficient of printed ABS and PLA samples in standard X-ray beams, verifying if phantoms printed with these materials could be an easier-handle substitute for PMMA, enabling the creation of different designs in an easier and cheaper way. Results show that PMMA presents higher attenuation coefficient, followed by PLA and ABS, which means that thinner PMMA layer creates higher radiation attenuation.Artigo IPEN-doc 21154 Teste de estabilidade dos sistemas de raios X do Laboratorio de Calibração do IPEN2015 - BARROS, ISRAEL D.; CORREA, EDUARDO L.; POTIENS, MARIA P.A.; VIVOLO, VITOR; SILVA, ERIC A.B.Artigo IPEN-doc 16951 Comparison of KVp and PPV measurements between a constant potential and clinical x-ray system used for calibration in mammography2011 - CORREA, EDUARDO de L.; VIVOLO, VITOR; POTIENS, MARIA da P.A.Artigo IPEN-doc 17470 Evolution of kVp adn PPV in mammography beams used for instruments calibration changing the additional filtration material2011 - CORREA, EDUARDO de L.; POTIENS, MARIA da P.A.; VIVOLO, VITORArtigo IPEN-doc 17473 Quality control methodology and implementation of X-radiation standards beams, mammography level, following the standard IEC 612672011 - CORREA, EDUARDO de L.; VIVOLO, VITOR; POTIENS, MARIA da P.A.Artigo IPEN-doc 17459 Determination of the effective energy in X-rays standard beams, mammography level2011 - CORREA, EDUARDO de L.; VIVOLO, VITOR; POTIENS, MARIA da P.A.Artigo IPEN-doc 15011 Comparison between different kinds of additional filtration in standards x-ray beams, mammography level2009 - CORREA, EDUARDO de L.; VIVOLO, VITOR; POTIENS, MARIA da P.A.Artigo IPEN-doc 20142 Determination of the effective energy in X-rays standard beams, mammography level2012 - CORREA, EDUARDO de L.; VIVOLO, VITOR; POTIENS, MARIA da P.A.
