Assessment of Conventional X-Ray Machine Anode Heel Effect

Abstract

This study used to evaluate the effect of anode heel in conventional X-ray tube Abstrac in image quality femur and humerus dry phantom are exposed, the image was obtained using dry phantom in the Modern Medical Center, Antalia Center , Ear Nose and throat hospital with marks in anode side and cathode side. A total of 10 images was obtained using dry phantom, the exposure factors used to obtain the image, 50 (Kvp), 5 current time product (mAs), and the ESDs was established at a reference point of 100 cm from tube focus for the range of current time product (mAs) and tube potentials encountered in clinical practice. The main results were that the densities increase toward cathode except in digital radiography, which are the same identify in literature, also the variation in densities is due to the variation in x-rays intensities but this does not affect on image quality especially in DR, due to wide capability of post processing of the image which result in enhancing image contrast and visibility and reduced the effect of variation. IV x-ray intensities
