Otimização da técnica de exposição para exames radiográficos de pelve em sistemas de Radiologia Computadorizada (RC)

Abstract: Neste estudo, verificou-se a influência da técnica de exposição na qualidade da imagem (QI) na perspectiva da redução da dose de radiação para exames radiográficos de pelve em sistema de Radiologia Computadorizada (RC). Para simular o exame radiográfico utilizou-se um fantoma antropomórfico representando a anatomia da região da pelve de um paciente adulto. Usou-se um equipamento radiográfico CR para aquisição das imagens, as medidas dosimétricas obtidas com câmara de ionização em quatro técnicas distintas. Com… Show more

“…The choice of this phantom was based on the fact that the imaging techniques used to obtain images are the same as those applied in human pelvic radiography. Additionally, the phantom reproduces images similar to those of a human pelvis, making the experiment closely resemble a real radiographic examination [9].…”

“…Anthropomorphic Phantom: For the experimental measurements, an anthropomorphic phantom was utilized. The simulator was designed and developed specifically by students of the Medical Physics course at the Universidade Franciscana (UFN) and consists of reproducing the image of the pelvis, it was validated by the study by Gomes et al, 2022 [9]. It accurately represents the anatomical structures of the abdomen region, including the lumbar spine and pelvis, and is covered with acrylic resin to simulate a typical adult.…”
