Breast Cancer Detection via Two-dimensional Ultrasound Tomography

In the framework of biomedical imaging, ultrasound tomography has recently proven to be an attractive solution for non-invasive, non-destructive diagnostic imaging. More in detail, this technique exploits mechanical waves which are safe for the patient and can be considered for frequent screening. The aim of this technique is to retrieve the mechanical information of breast inner tissue via the analysis of pressure waves acquired by sensors surrounding the region of interest. In this paper a stepped breast-cancer-imaging approach via ultrasound tomography is proposed. The tumour extension and localisation are retrieved via solving a set of linear inverse scattering problems in a step-by-step fashion. The proposed approach seems to be promising in terms of malignancy identification.
