Introduction Radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. Therefore, entrance skin dose (ESD), body organ dose (BOD), and effective dose (ED) from adult patients undergoing routine thorax posterior-anterior (PA) and thorax right lateral (RLAT) were estimated in Uni...

Diagnostic radiology's basic task is to provide high quality diagnostic image information about anatomic detail or ongoing physiological process within patient's body, where such information can not be provided using alternative diagnostic method which excludes the use of ionizing radiation. Ensuring adequate clinical diagnostic information together with the least possible exposure of the patie...

background: there is an international emphasis on providing timely and high quality data to monitor progress of countries toward millennium development goals. iran’s multiple indicator demographic and health survey (irmidhs) aimed to provide valid information on population and health outcomes to monitor progress in achieving national priorities and health programs and to assist policy makers to...

There is considerable current interest in deriving accurate dimensional measurements of the internal ge ometry of complex manufactured parts particularly castings This paper describes an approach to the re construction of D part geometry from multiple dig ital X ray images A novel method for radiographic stereo is described which takes into account the spe cial imaging geometry of the digital X...

OBJECTIVE To determine the examination frequencies, quality of radiographic images and the entrance surface dose (ESD) in patients undergoing general radiographic examinations. DESIGN Prospective study on the device performance, film reject rate, patient dose, and image quality during the use of standard and fast speed film screen combination. SETTING Radiology Department of Kenyatta Nation...

Introduction Quality control (QC) techniques are used in monitoring and maintenance of the components of an x-ray system. QC of radiology devices plays a significant role in reduction of medication dose and optimization of image quality. This study aimed to conduct QC tests on randomly selected radiology devices, installed in diagnostic imaging departments of Iran. Materials and Methods In tota...
