[ 1 ] - برآورد دز موثر اندام های حساس به پرتو ناشی از آزمایشات قفسه سینه، با و بدون سیستم کنترل اکسپوژر اتوماتیک
Introduction: There are several techniques for reducing the delivered dose from CT scans such as the automatic exposure control (AEC). This technique regulates the tube current regarding the patient size and weight. The aim of this study was estimation the effective and equivalent dose for radiosensitive organs in women undergoing chest CT scans with or without AEC system using the patient&rsqu...
[ 2 ] - Measurement and comparison of head scatter factor for 9MV photon beam using the build-up cap and a columnar mini-phantom
Introduction: The Sc is an important parameter to monitor unit (MU) calculation in radiation therapy procedure. The aim of this study is to measurement and comparison of head scatter factor (Sc) for 9MV photon beam using the build-up cap and a columnar mini-phantom. Materials and Methods: The measurements performed using a calibrated ion chamber (Scanditron...
