Effects of Exposure Factors on x-ray System Output

Abstract

The aim of this study was to study Effects of Exposure Factors on x-ray system Output . The measurements were carried out using Diavolt meter at different Kvp, mass, different FFD and the collected data have been analyzed by using Microsoft Excel soft ware. The analysis of data showed that: the general dose has been decreases with the increment of distance and the relation was fitted to the equation: y = -32.58x + 3815 refers to distance in cm and y refers to dose in Gy. And the dose has been increases following the increment of mAs for all applied distances and the relation has been fitted to equation: y = 26.57x + 12.93, where x refers to mAs and y refers to dose in Gy. Also the result showed that: the dose has been increases following the increment of KVp for all applied distances and the relation has been fitted to equation: y = 36.93x – 1244, where x refers to KVp and y refers to dose in Gy.
