SUMMARY:

Breast cancer is one of the main causes of death amongst women. Its mortality ratio is directly proportional to the stage in which the tumor is detected. If detected in its early stage, the 5 years survival rate is above 90\%, making early detection of upmost importance. Currently X-Ray mammography is considered the gold standard for diagnosis. Despite being the most applied technique, X-Ray mammography has some drawbacks, like patient discomfort, high false positives and high false negatives rate, and high exposition to ionizing radiation. Due to the limitations of current techniques, microwave imaging has risen as a complementary imaging modality due to its high sensibility to cancer diagnoses due to the contrast between dielectric properties of heath tissue and tumorous tissue in the microwave region. In this work we present a new tomography system where robotic arms are used to position the antennas around the breast using information obtained from a depth camera, resulting in bigger flexibility and patient comfort. The system was tested using breast phantoms and was capable of detecting and locating the tumor. Beyond that it was demonstrated the possibility of mobile usage utilizing low-cost single board computers; the possibility of utilizing cloud computing to offset computationally heavy tasks; the possibility of the utilization of real-time imaging for decision making in regard to antenna positioning.
