Abstract
The purpose of this study is evaluated scatter radiation in digital radiological condition by using photo-stimulated luminescence (BaFBr:$Eu^{2+}$). Experiment condition changed kVp (from 50 kVp to 120 kVp), filed size (from $4{\times}4cm^2$ to $26{\times}26cm^2$) and phantom thickness (from 1 cm to 15 cm). This method was analysed ImageJ and characteristic curve of CR. This results was scatter radiation to primary radiation ratio increased from 50 kVp to 70 kVp, and it was fixed at over 80 kVp. The scatter radiation to primary radiation ratio are increased according to increasing the ratio of field size. Scatter radiation is also increased by increasing the phantom thickness.
