Innovative X-ray and Radar Technology Reduces Risks in Cancer Screening

Recent advancements in medical imaging are paving the way for safer and more accurate cancer detection methods. Researchers from the Fraunhofer-Gesellschaft have developed a pioneering approach that combines traditional X-ray imaging with radar technology to minimize radiation exposure during diagnosis and monitoring of breast and lung cancers.

While X-ray mammography remains the standard for early breast cancer detection due to its speed and precision, it involves exposure to ionizing radiation. High doses from more advanced imaging like CT scans pose health risks, especially with repeated use. To address this, the Fraunhofer team is exploring a multimodal imaging system that merges X-ray data with radar signals, which are well-known outside the medical field for their applications in aviation and automotive industries.

Radar offers a low-risk alternative to obtain three-dimensional images by detecting differences in tissue electrical properties without radiation. Despite lower resolution compared to X-ray, radar can reveal vital tissue changes, especially when integrated correctly with other imaging methods. The team is working on sophisticated algorithms to accurately align (or 'co-register') radar and X-ray data, enhancing the clarity and detail of internal tissue visualization.

This approach involves developing special imaging phantoms—artificial models mimicking human tissue—to test and optimize the combined system. The goal is to create a comprehensive, multimodal lab setup capable of early detection of tissue abnormalities with high precision and reduced radiation dose.

This innovative method not only aims to improve diagnostic accuracy but also significantly reduces the physical and health burden on patients. In a three-year project, the research team envisions a future where cancer screening is safer, more effective, and less invasive.
