Evaluation of the Influence on the Use of Additional Filtration in Pelvic Radiographic Examinations Using a Phantom Object

Aims: This study aimed to determine the effect of additional filtration on image quality and dose reduction in pelvic radiographic examinations.
 Study Design: Mention design here.
 Place Duration Study: The research was conducted at a municipal emergency service radiology department Rio Grande do Sul, Brazil.
 Methodology: Using simulator object replicate clinical examination conditions. equipment fitted with aluminum, copper, copper-aluminum composition filters identify optimal for reducing radiation doses maintaining quality.
 Results: Results showed that effectively reduced average absorbed internal organs, greatest observed copper filter. However, excessive resulted decrease quality, particularly Figure Merit (FOM) demonstrated keeping electrical factors X-ray tube consistent (70 kVp 32 mAs) using an 2.5 mmAl filter could optimize examinations, based diagnostic IQ criteria established by service.
 Conclusion: In conclusion, FOM revealed tube's 70 mAs reduce KERMA air 49.8% patient, 41.5% testes, 35.5% bladder, 30.4% ovaries, 29.7% bone marrow, 35.3% total effective examination, while equivalent quality.
