Radiation Dose<\/p>\n\n\n\n\n\n
Measuring the mean glandular dose (MGD) to the standard breast has for many years been the main means of assessing the doses from mammographic systems. Although this is a valuable and simple approach to dose measurement it provides limited information on the doses received by individual women. Consequently the periodic measurement of doses for samples of women undergoing mammographic examinations is recommended. NCCPM have ran a number of national dose surveys every 3 years since 1998 (see publications).<\/p>\n\n\n\n

New Dose Model<\/p>\n\n\n\n
The current doses are based on methods Developed by Prof David Dance. There is now an alternative dose model published by Sechopoulos et al (Med Phys 2023) as part of the AAPM TG282\/ EFOMP Working Group. The NCCPM equipment database will calculate doses for Dance and TG282 models. NCCPM hosts a dose calculator for TG282 on:<\/p>\n\n\n\n
