Compression forces used in the Norwegian Breast Cancer Screening Program (2017)
Journal Article

Objectives: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the Norwegian Breast Cancer Screening Program (NBCSP), the recommended range of compression force for f...

Health behavioural theories and their application to women’s participation in mammography screening : a narrative review (2017)
Journal Article

The most effective method of detecting breast cancer amongst asymptomatic women is by mammography screening. Although, most countries have this preventive measure in place for women within their society; most of these programmes still struggle with w...

Development of a phantom to test fully automated breast density software – a work in progress (2016)
Journal Article

Objectives: Mammographic density (MD) is an independent risk factor for breast cancer and may have a future role for stratified screening. Automated software can estimate MD but the relationship between breast thickness reduction and MD is not fully...
