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

---

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