introduction interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. the effect of applicator attenuation is not considered in dose calculation method released by aapm-tg43. in this study, the effect of high-dose rate (hdr) brachytherapy esophageal applicator on dose distribution was surveyed in hdr brachytherapy. materials and methods a cylindrical pmma phan...
Because of the need for decentralization in the Iran's centralized planning system, planners and experts have always been thinking about planning decentralization, provincial development and defining legal and institutional frameworks for it. It is to be noted that although outstanding efforts have been made during the recent years especially within Iran's third development plan years, provinci...
an important need in radiation therapy is a fast and accurate treatment planning system. this system using ct data and characteristics of the radiation beam, calculates the dose in all points of the patient’s volume. two main factors in planning system are “accuracy” and “speed”. according to these factors, various generation of treatment planning systems are developed. this article is the re...
introduction intensity modulated radiation therapy (imrt) has made a significant progress in radiation therapy centers in recent years. in this method, each radiation beam is divided into many subfields that create a field with a modulated intensity. considering the complexity of this method, the quality control for imrt is a topic of interest for researchers. this article is about the various ...
