Assessment 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 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...
متن کاملAverage Glandular Dose and Entrance Surface Dose in Mammography
In general, dose evaluation for mammography uses average glandular dose (AGD). In mammography, entrance surface dose (ESD) is high, which is well known, but actual clinical data of ESD are not reported so much. This study investigated AGD and ESD for patients whose doses were estimated from 200 mammography examinations using European Organization for Quality-Assured Breast Screening and Diagnos...
متن کاملAssessment of Mean Glandular Dose in Mammography System with Different Anode-Filter Combinations Using MCNP Code
BACKGROUND X-ray mammography is one of the general methods for early detection of breast cancer. Since glandular tissue in the breast is sensitive to radiation and it increases the risk of cancer, the given dose to the patient is very important in mammography. OBJECTIVES The aim of this study was to determine the average absorbed dose of X-ray radiation in the glandular tissue of the breast d...
