We are inspired to improve mammography


Worldwide, circa 150 million mammographic examinations are performed every year. To get the best image quality with the least amount of radiation, the breast needs to be compressed.

We developed a patented technology for a highly reproducible procedure without unnecessary discomfort. An optimized breast examination contributes to the early detection of cancer which ultimately can saves lives.

2016 - Performance of Breast Cancer Screening Depends on Mammographic Compression
Breast Cancer detection and Positive Predictive value (PPV) are 20-30% significantly better with the highest PPV at compression pressures between 9.18 kPa, and 10.7 kPa; this correspondents to approximately with 75 mmHg. These results strongly support the hypothesis that there is an optimal pressure during breast compression...
2016 - Force balancing in mammographic compression
Skin stretching is often regarded as an inevitable side-effect of mammographic breast compression, but this study shows that much unnecessary stretching can be avoided by adequately adjusting the position of the X-ray image receptor to the height of the patient...


Annual Symposium Breast Screening Belgium. February 4, 2017, Bruges, Belgium
During the annual symposium Breast Cancer Screening in Belgium Sigmascreening will give a presentation on pressure-based breast compression. In this lecture we go deeper into the question whether optimal compression leads to better image quality which leads to an improved detection of breast cancer?

2016 Oct - Pressure controlled compression of the breast in mammography
Recent results show that the performance of mammography, in terms of detect- ability of cancerous lesions can be affected by the compression pressure at which the examination is carried out. This article describes the rationale behind the development of a pressure-based compression system. (First published in DIEurope October 2016)
