Optimasi Penggunaan Faktor Eksposi Pemeriksaan Ossa Manus dengan Kualitas Citra Objektif dan Subjektif

<p>In producing a good radiographic image, an optimization method is needed. This study was conducted to seek of the examination manus ossa with objective and subjective image quality analysis. The research quantitative experimental, using variety exposure factors: 40kV 4 mAs, 10 46 kV 5 53 2,5 61kV 1,25 mAs. Then analysis carried out by measuring pixels value, Signal Noise Ratio (SNR), Exposure Index (EI) value as indicator exposure. For assessment anatomy criteria Visual Grading Analysis (VGA), then test Wilcoxon determine relationship respondents VGA assessment. results obtained that at factor mAs range pixel 183,7 - 3, SNR 12,2-1,77 while all images on factors can be used in establishing diagnosis. lowest EI p-value>0,05 so there no difference 2 radiographers, therefore variations could manus.<em></em></p>
