Abstract

Telah dilakukan penelitian tentang pengaruh kecepatan penguatan lembar penguat terhadap densitas, pada pengambilan radiograf dalam menega.kkan \diagnosa. Pengaruh kecepatan penguatan lembar penguat terhadap Aggsitas, diperoleh melalui pengukuran nilai eksposi pada densitas yang hampir sunk, untuk jenis lembar penguat kecepatan tinggi, kecepatan sedang dan keccwAr rendah dengan obyek stepwedge. Hasil penelitian ini menunjukkan, bahwa lembar penguat jenis kepp sedang memerlukan 2 kali lebih besar nilai eksposi dan lembar pew, at kecepatan tinggi, sedangkan lembar penguat kecepatan rendah memerlukan 1,5 kali lebih besar nilai eksposi dari lembar penguat kecepatan sedang Kata kunci : faktor eksposi (V. .t), densitas, eksposi (dosis radiasi). A research about influence of intensifying speed of the intensifying screen to density on a radiograph in diagnose has been done. The influence intensifying speed of the intensifying screen to density has been curried out by measuring the exposure values at the same densities for intensifying screen high speed, medium speed and low speed with stepwedge as object. The result of this research indicated that the intensifying screen medium speed is needed 2 times greater exposure value than intensifying screen high speed, while intensifying screen low speed is needed 1,5 times greater exposure value than intensifying screen medium. Keyword : Exposure factor (V.i.t), density, radiation dose.
