Ultrasound Computed Tomography (USCT) is a novel imaging method with high potential for early breast cancer diagnosis. It promises high sensitivity and specificity for early breast cancer detection without the associated risks of ionizing radiation and lower costs than magnetic resonance tomography. The aim of the project is to investigate a new method for early breast cancer diagnosis: high-resolution transmission imaging via USCT. We consider various machine learning methods including deep learning strategies to help improve the imaging performance.
The image acquisition of USCT is based on ultrasound transducers surrounding the breast within a water bath (Figure 1 shows a typical USCT machine for clinical application). We investigate deep learning techniques to reconstruct high-resolution images according to the acquired data. The parts of reconstructed images are shown in Figures. 2-3.
