Abstract

Telah dilakukan penelitian tentang analisa panjang focal spot efektifjarak fokus ke film, serta jarak obyek ke film terhadap ketidaktajaman geometri (Ug). Ketidaktajaman geometri (Ug) dianalisa dengan membandingkan hasil secara teori dan hasil eksperimen. Nilai ketidaktajaman geometri hasil eksperimen diperoleh dari radiograf melalui pemotretan sinar-x terhadap obyek lempengan timah dengan cara memvariasi panjang focal spot efektif dengan jarak fokus ke film dan jarak obyek ke film tetap, variasi jarak fokus ke film dengan panjang focal spot efektif dan jarak obyek ke film tetap, serta variasi jarak obyek ke film dengan panjang focal spot efektif dan jarak fokus ke film tetap. Hasil penelitian antara teori dan eksperimen membuktikan, semakin besar panjang focal spot efektif dan jarak obyek ke film, serta semakin kecil jarak fokus ke film akan diperoleh nilai ketidaktajaman geometri semak It has been done study experimental about effective focal spot size ,the distance focus to film, also the distance object to film toward geometric unsharpness (Ug). Geometric Unsharpness (Ug) is analyzed by comparing theoritically outcome and experimently one. The value of geometric unsharpness of experiment outcome was get from radiograph through x-ray photograph toward plaque of tin object by making variation of effective focal spot size with the distance focus and film and the distance between object and film is constant ,the variation of distance between focus and film with effective focal spot size and the distance between object and film is constant, and also variation of distance between object and film with effective focal spot size and the distance between focus and film is constant. The result of the study between theory and experiment show that the greater size of effective focal spot and the distance between object and film,and also the smaller the distance between focus and film, will get value of geometric unsharpness is greater. in besar.
