Abstract

Given the large number of new cases of breast cancer worldwide every year and the limitations of the current imaging techniques by absorption in providing the early diagnosis of this disease, which would increase the chances of cure, new imaging modalities have been studied in order to complement the information provided by them.In this sense, the purpose of this project is to study tomographic imaging techniques based on the x-ray scattering phenomenon by the tissues that compose the breast. The tomographic images by x-ray scattering enables, in addition to a three-dimensional inspection of the entire breast volume, a better definition of contours, by means of the diffraction enhanced imaging (DEI) technique, higher contrast between tumor and healthy tissue, using the imaging X-ray diffraction imaging (XRDI) technique, and information about the spread of cancer at molecular scale, from the small angle x-ray scattering imaging (SAXSI) technique. Yet, the information obtained from images of a sample will be correlated with those from histological sections. Finally, we will evaluate the combination of these techniques simultaneously in the same experiment. This type of study is potentially important in healthcare because is associated with the study of new radiological techniques that would complement the information of current imaging techniques and then improve the diagnostic capability of breast cancer.
