[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 کاملQuality 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 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...

Evaluation 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) ...
