Objective: Investigate the correlation between radiation dose and radiation risk when patients are scanned by 64-slice spiral CT. Materials and Methods: Using SPSS 17.0 statistically analyze the patient’s scanning parameters, radiation dose of monitoring and examining the patients who are scanning of their abdomen, chest and pelvic in our affiliated hospital. Results: SPSS statistical analysis ...

Health problems after a nuclear crisis are aninteresting issue in medicine. After the recentJapanese nuclear crisis, several health issuesunderwent monitoring. There are few considerationson mucocutaneous diseases. Indeed, there is nodoubt that the skin and mucocutaneous issues arethe main organs affected by leaked radiations. It isimportant to take care of mucocutaneous lesionsin acute radiati...

IntroductionA fine balance of image quality and radiation dose can be achieved by optimization to minimize stochastic and deterministic effects. This study aimed in ensuring that images of acceptable quality for common radiographic examinations in digital imaging were produced without causing harmful effects. Materials and MethodsThe study was conducted in three phases. The pre-optimization inv...

OBJECTIVE To evaluate the accuracy, utility, and cost effectiveness of a new electromagnetic patient positioning and continuous, real-time monitoring system, which uses permanently implanted resonant transponders in the target (Calypso 4D Localization System and Beacon transponders, Seattle, WA) to continuously monitor tumor location and movement during external beam radiation therapy of the pr...
