Studi perbandingan karakteristik film sinar X emulsi tunggal dan emulsi ganda

Abstract

Telah dilakukan penelitian Studi Perbandingan kurva karakteristik film Sinar-X Emulsi Tunggal dan Film Sinar-X Emulsi Ganda. Penelitian dilakukan dengan menggunakan 10 lembar film sinar X emulsi tunggal dan 10 lembar film sinar-X emulsi ganda. Dengan menggunakan pesawat sinar-X konvensional setiap film dipaparkan.Metode yang digunakan dalam penelitian ini adalah metode skala waktu, dengan faktor paparan : tegangan tabung 45 kV, arcs tabung 100 mA, jarak fokus ke film 90 cm dan wakta paparan (s) bervariasi. Basil percobaan menunjukkan bahwa peningkatan waktu paparan dapat meningkatkan densitas pada film_ Hasil pengukuran densitas adalah densitas pada film emulsi ganda mempunyai nilai lebih tinggi dari film sinar X emulsi tunggal, sehingga kemiringan garis linier pada film sinar-X emulsi ganda yang terlihat pada kurva karakteristik, lebih curam daripada film sinar —X emulsi tunggRl. lni berarti bahwa nilai gamma (y) pada film sinar-X emulsi ganda lebih besar dari film sinar-X emulsi tunggal. It has been doing a research about The Comparing Study of the Characteristic Curve of Single Emulsion X-Ray Film and Double Emulsion X-Ray Film. This experiments was uses 10 pages single emulsion X-Ray film and 10 pages double emulsion x-Ray film. Using convensional X-Ray equipment, each film is exposed_ The method that used in this research is time scala method, with exposure factors : the voltage is 45 kV, tube current is 100 mA, distance. focus to film is 90 cm, and various exposure times in second. The result of experiment shows that increasing exposure time can cause increasing density of film. The result of the measuring of density that the density of double emulsion x-Ray film has higher value than single emulsion X-Ray film, so the gradient of double emulsion X-Ray film that seen at the characteristic curve, is steeper than single emulsion X-Ray film. It is mean that gamma (y) value of double emulsion X-Ray film is large than
