In order to improve breast cancer detection rates, new and better imaging methods are required. Currently, the ultrasound tomography (UT) as non-invasive and safe hybrid method may contribute to achieving a new standard for breast cancer diagnostics. The aim of the paper was to analyse the imaging ability of tissue-like media structure found in female breast using the developed novel ultrasound computer-assisted tomographic scanner. Measurements was performed on commercial breast biopsy phantoms due to their well-defined structure with inclusions mimicking glandular tissue with lesions, as well as on the simple agar phantom. Obtained magnetic resonance images (MRI), conventional ultrasound images (US) or X-ray computed tomography (CT) images of the measured media sections were used for comparison. The analysis of the obtained results and carried out theoretical considerations have allowed to estimate the resolution of soft tissue UT imaging.
