Studi Penentuan Titik Fokus pada Uji Akurasi Tegangan Tabung dalam Proses Kalibrasi Pesawat Sinar - X

The research about Study Detemination Focusing of the Test TubesAccuracyVoltageIn Process Calibration X-ray tube. Using a multimeter piranha with the selection ratio standard positions 0.995, 1.000 and 1.005 and a varietion of factors eksposi 50, 70 and 90 kV, with the intentiondetermining perpendicular among the focal point of the detector and determine accuracy reading of the multimeteraccuracyvoltage kV testing. \ud The results of this study show that degree of accuracy for the test X-ray tube used selection ratio posision of 1,000, because is no deviation between the center point of the detector with the center point X-ray beam
