Preliminary study of human breast tissue using synchrotron radiation combining WAXS and SAXS techniques.
Using synchrotron radiation, we combined simultaneously wide angle X-ray scattering (WAXS) and small angle X-ray scattering (SAXS) techniques to obtain the scattering profiles of normal and neoplastic breast tissues samples at the momentum transfer range 6.28 nm(-1)<or=Q(=4pi x sin(theta/2)/lambda)<or=50.26 nm(-1) and 0.15 nm(-1)<or=Q<or=1.90 nm(-1), respectively. The results obtained show considerable differences between the scattering profiles of these tissues. We verified that the combination of some parameters (ratio between glandular and adipose peak intensity and third-order axial peak intensity) extracted from scattering profiles can be used for identifying breast cancer.
