A Proposed Simple Teleradiology System Using a Digital Camera

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...
