Quality Assurance and Average Glandular dose Measurement in Mammography Units
To ensure the safe operation of mammography units, acceptance tests and quality assurance (QA) protocols have been developed by the American Association of Physicists in Medicine (AAPM), Engineers Registration Board, and International Atomic Energy Agency. Eight mammography units manufactured by five different manufacturers located in hospitals in our region were investigated following the AAPM...
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 کامل[Investigation of quality control and average glandular dose and image quality in digital mammography in Hokkaido].
A questionnaire survey about mammography in Hokkaido was mailed to 121 facilities from August to September 2009. We surveyed the conditions of digital mammography with regard to quality control (QC) and average glandular dose at 79 facilities in Hokkaido in 2009, and the results of the survey were compared with those of 2004. We found that digital mammography techniques were widely used across ...
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 کاملAssessing Image Quality and Estimating the Glandular Average Dose in Some Mammography Labs
Mammography is the safest method of detecting breast cancer but, at the same time, the most exacting radiological examination which implies getting high quality images and a minimum dose per breast. The present study was carried out in six mammography laboratories, from which only one has partially implemented a programme of quality control. There were evaluated the phantom image, film contrast...
