Breast cancer early detection by ultrasound Computer tomography

Breast cancer is the most common cancer among women: 1,600,000 breast cancers occur worldwide each year. Although the breast is not a vital organ, the chances of recovery are not as good as they could be. Recognized and localized in good time, breast cancer is very well treatable. The Ultrasound Computed Tomography (USCT) project is developing a novel breast cancer screening technology that promises high-resolution three-dimensional images. Our goal is to discover a tumor with the average size of 5 mm in order to enable an earlier diagnosis time and thus greatly increase the chances of recovery. Since the method is based on ultrasound, it offers many advantages.

In terms of technology, the project poses a great challenge. The process is based on thousands of ultrasonic transducers arranged in a water-filled examination basin. When capturing an image, large quantities of raw data are generated, which are then used to reconstruct various 3D images. Learn more about the functional principle of USCT.

For the prototype development we can fall back on the competences of our institute: from the mechanical planning over the sensor construction, the structure of the analog and digital electronics up to the software development the complete development of the system is carried out in our house. In numerous subprojects we additionally cooperate with national and international partners.

Currently, the second 3D-USCT prototype is being tested in a clinical study at the University Medical Center Mannheim.
