Comparison Between Film-Screen and Digital Mammography for Woman Breast Cancer Screening: Mean Glandular Dose
Introduction: Most studies in mammography have only been carried out in a comparison of image quality and lesion detection in film-screen mammography (FSM) and full field digital mammography (FFDM) systems. The aim of this paper was to evaluate mean glandular dose (MGD) of patient and affecting factors by FSM and FFDM to estimate which one gives a brief radiation protection to patient. Material...
متن کاملAssessment of mean glandular dose in mammography.
The routine assessment of patient dose in the National Health Service Breast Screening Programme is performed as part of the quality assurance protocol recommended by the Institute of Physical Sciences in Medicine. The mean glandular dose to a standard breast is deduced from measurement of the air kerma at the entrance surface of a 4 cm Perspex phantom by applying a series of conversion factors...
متن کاملEstimation of Mean Estimation of Mean Glandular Dose in Mammography Examination in some of Radiology Centers in Tehran city
Introduction: the objectives of this research were determination of Mean Glandular Dose in film- screen and digital mammography examinations, estimation of accumulated effective dose in some of mammography centers in Tehran city and estimating cancer risk due to these examinations. Materials and Methods: the clinical data were collected from the 1318 <...
متن کاملEstimating average glandular dose in routine mammography screening using neural network
Given the extensive use of common mammography tests for screening and diagnosis of breast cancer, there are concerns over the increased dose absorbed by the patient due to the sensitivity of the breast tissue. Thus, knowing the Mean Glandular Dose (MGD) before radiation to the patient through its estimation can be helpful. For this reason, the MultiLayer Perceptron (MLP) neural network model wa...
متن کاملassessment of mean glandular dose in mammography system with different anode-filter combinations using mcnp code
conclusion by comparing the results, we saw that w/rh anode/filter combination is the best choice in breast mammography imaging because of the lowest delivered dose in comparison with w/ag and rh/al. moreover, breast thickness and g value have significant effects on mgd. objectives the aim of this study was to determine the average absorbed dose of x-ray radiation in the glandular tissue of the...
