conclusions in this study radiology students believed digital radiology can enhance the production efficiency and quality of the images. they also had the right information about digital radiology. however, it is recommended in order to prevent the emergence of problems caused by change of radiology equipment and efficiency of the professional in-service training the theoretical training needs ...

Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

Background and Purpose:  Due to the important role of imaging in the diagnosis and treatment plan in orthodontics, CBCT (Cone Beam Computed Tomography) images because of their three-dimensional nature, can minimize the disadvantages of two-dimensional images such as magnification, distortion, or superimposition. The purpose of this study was to evaluate the accuracy of conventional cephalograms...
