Analisis Variasi Ekspose terhadap Kontras Jaringan Lunak (Soft Tissue) dengan Menggunakan Radiografi

Abstract

It had been research to measure factor exposition to soft network base used X-ray craft with variation of tube tension (kV) and Current (mAs). Experiment is conducted with object irradiating soft tissue, at condition of tube tension variation 42 kV, 46 kV, 52 kV, 57 kV and 63 kV with current fixed namely 8 mAs. Then assessed density by using densitometer. Highest contrast for variation of tube tension are 42 kV as high as 0.69, Contrast lowest value for variation of tube tension namely 63 kV as high as 0.06. And then research continue with current variation 2 mAs, 4 mAs, 7 mAs, 8 mAs and 10 mAs with tube tension fixed namely 46 kV. Whereas highest contrast value for current variation is 4 mAs as high as 1.15, contrast lowest for current variation is 8 mAs as high as 0.30. Universitas
