My research project
A methodology for breast density measurement using the HEXITEC pixellated spectroscopic technologyBreast tissue is a mixture of adipose tissue and glandular tissue. Breast density is defined as the volume fraction of glandular tissue within the breast. Having a higher breast density has been shown to increase the likelihood of developing breast cancer. It is therefore important to measure breast density, in order to identify those who are at greatest risk (to screen them more often) and those who are at less risk (to screen them less often, saving resources).
The HEXITEC detector registers the position and energy of X-rays incident upon it. This projects aims to utilize the energy information provided to differentiate between adipose and glandular tissue within a breast, in order to measure breast density.
