The Effect Of Exposure Index Variations On Subjective Quality Assessment On Lumbosacral Examination

Exposure index (EI) is an indicator of dose used to determine overexposed, optimal and underexposed images so that this study discusses the effect EI variations on subjective image quality assessment lumbosacral examination. This research uses descriptive quantitative method by filling out questionnaires calculating radiation output dose. Then draw conclusions, perform a visual grading analysis (VGA) statistical test using one-way ANOVA test. The results obtained varying for AP projections 2.99 (overexposed), 2.79 (optimal), 2.33 (underexposed) then Lateral 2.91 2.76 2.46 (underexposed). Furthermore, calculation equation produces 3.158 mGy 0.78 (optimal) 0.57 projection while lateral it 3.61 1.52 (optimal). , get conclusion, VGA was carried testing, data generated after performing tests showed 0.87 0.612. Based has been out, conclusion all respondents have same with overexposed better than indicator.
