The effect voltage Device of x-ray on radiation doses and image quality

Abstract

Abstract The X-ray tube generates diagnostic X-rays, and these rays can penetrate the human body and to different dimensions depending on the energy of the rays. These rays meet absorption and scattering inside the body, and whatever comes out of them is used for radiological examination purposes. Radiation exposure accompanies some of the potential risks, so it requires knowing the amount of radiation dose for the total exposed (man. Sv), as well as the equivalent effective dose for the organ or tissue in the body, and multiplied by the value determined by the risk factor, thus determining the amount of radiation risk or the rate of infection Radiative damage. The surface entry dose values measured by the German-born Dosimax mobile device are closer to the reference values, because the sensitive size of this meter is a material equivalent to living tissue, which is exposed to X-rays, so the reading value of the dose in the air is not the same as in the case of the ionization chamber (Unfors) is Swedish in origin, but rather the dose of live tissue which is an approach to the dose of patients. The amount of fluctuation in the measuring voltages of the device (C) is 11.3% which is higher than the specified values, and also the standard deviation in the measurement is more than 5%, that is, the device does not meet the quality assurance specifications (QA), while the two devices (F, E) are The volatility value is 3.89% and 4.6%, respectively, which is less than the limits set for this fluctuation of 10%, and the standard deviation values are less than 5%.
