Avaliação do kerma no ar na superfície de entrada e da qualidade da imagem em radiografias de tórax

Abstract: OBJETIVO: Avaliar os fatores de técnica utilizados durante exames de tórax póstero-anterior em pacientes-padrão e correlacioná-los aos valores de kerma no ar na superfície de entrada e à qualidade das imagens clínicas. MATERIAIS E MÉTODOS: O estudo foi realizado em três hospitais do Rio de Janeiro, num total de cinco salas de raios X, com dez pacientes por sala. As imagens foram avaliadas pelos radiologistas dos serviços segundo o protocolo europeu. O kerma no ar na superfície de entrada foi estimado a partir … Show more

“…Additionally, the utilization of reference dose levels defined by the Order (Portaria) No. 453 (12) of the Brazilian Ministry of Health is suggested, for the examinations to be performed in the recently installed systems, in order to assure that the dose to the patient is the lowest possible (1,13) . This way, the radiological protection ALARA principle will be efficiently applied.…”

“…Because of such these differences intrinsic to the digital imaging technology, an appropriate calibration of these systems is critical to obtain the lowest dose required to achieve diagnostic image quality and thus benefiting from the advantages of this technology. Some authors, among them Souza et al (1) , have published studies on this subject.…”
