It has become an inevitable development that X-ray digital imaging detectors replace film-screen. The imaging quality of X-ray digital detector could not reach the level of film-screen due to its unique characteristics. It is the key that to research the method of improving and optimizing the digital imaging quality. The main factors to impact X-ray digital imaging quality is inherent non-unifo...
Introduction: Paediatric patients deserve special attention because of the higher radiation risks compared with adults. The main purpose of this study is to determine patient dose and diagnostic reference level for Paediatric through Entrance Surface Dose (ESD) calculations in common X-ray examination and to establish Paediatric national DRLs in digital radiography in Iran. <...
Knowing patient exact dose during radiological activities is considered as one of the main principles to decrease radiation-induced dangers which are not really necessary and affect a great deal of people. In this respect, in recent years many extensive studies have been done on types of photodiodes and production of X-ray detectors using semiconductor elements. Since these elements are not ver...
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
