Evaluation of glandular dose in mammography in the presence of breast cyst using Monte Carlo simulation
Introduction: Average glandular dose (AGD), entrance skin air kerma (ESAK) and normalized glandular dose (DgN) are the main dosimetric quantities in mammography. In this study, DgN is evaluated in the presence of breast cyst, which is a common disease among women and the influence of size, number and location of the cysts on the DgN is investigated. Materials and Meth...
متن کاملEvaluation of the relation between breast glandular absorbed dose and radiographic quality in mammography
Background: Breast is one of the main radiological sensitive organs, hence it is important to evaluate absorbed dose to this organ especially to the glandular parts. It is the aim of this study to measure mean glandular dose and image contrast in terms of different mammographic parameters. Materials and Methods: In this study two mammography machines located at Said-al Shohada (Giotto) ...
متن کاملClinical evaluation of breast dose and the factors affecting breast dose in screen-film mammography.
PURPOSE To investigate the factors affecting the mammographic breast dose. MATERIALS AND METHODS The assessment was done on 622 qualified mammograms obtained with use of "variable kV" technique, i. e., semiautomatic mode, in screen-film mammography. Actual breast doses were calculated and analyzed to determine the roles of two screens and three films, two anode/filter selections (Mo/Mo and Mo...
