Microwave radiation is the section of the electromagnetic spectrum beyond radio waves, usually having frequencies from 300 MHz (0.3 GHz) up to 300 GHz. These waves have been known for a long time and have been harnessed to improve applications such as communications (satellite, TV, Bluetooth, etc.), radar, radio astronomy and, of course, home cooking.
Microwave radiation is an extremely favourable method for screening of cancer because it carries lower energy compared to X-rays, thus being safe, non-ionizing and without side effects for the human body. These features allow frequent patient screening which is especially important when monitoring younger individuals.
Microwaves detect the presence of tumours via an inverse scattering process, i.e. by analysing the scattered radiation caused by the difference in materials (permittivity) between cancer cells and muscle or fat tissues.
MediWiSe develops microwave imaging systems specifically designed to detect early-stage breast and prostate cancer tumours with millimetre accuracy which are cheap, simple to use by non-experts and fully safe for frequent screening on a regular basis. Using state-of-the-art metamaterial technology and advanced time-reversal extraction algorithms, MediWiSe systems offer an affordable and user-friendly approach to quick and pain-free cancer monitoring and detection.
