Abstract

Telah dilakukan analisa pengaruh perbandingan antara ukuran focal spot dengan obyek (f/d) terhadap magnifikasi radiograf (M). Analisa ini dilakukan dengan obyek berupa koin terbuat dari besi yang ukuran diameternya berbeda-beda dan dengan memvariasi ukuran focal spot. Eksperimen dilakukan pada dua keadaan jarak obyek ke film yairu pada 0 cm (obyek menempel film) clan 30 cm. Hasil eksperimen menunjukkan peningkatan nilai f/d tidak disertai dengan meningkatnya nilai M ketika jarak obyek ke film adalah 0 cm (b=0), tetapi ketika jarak obyek ke film /chili hesar dari 0 (b>0) diperoleh peningkatan nilai lid yang disertai meningkatnya nilai M secara linear. It has been analysed that the influence of the ratio focal spot size to object O%1) to radiograph magnjfication ( ), Thia analysis has done with the object shape like a coin made from iron which different diameter aml to variation focal spot size. The experiment has done on two condition that the distance oldie object to the film, at 0 cm (object stick the film) and 30 cm. The experiment showed that the increasing old wasn't accompanied the increasing of M when the distance of the object to the film is 0 cm (b=0) but when the distance is more than 0 (b>) it will be resulted in the increasing of fi'd's rate which is coinpanied with in the increasing ofM.
