Carbon Nanotube Array Opens Door for Terahertz Radiation in Medical Practice

Terahertz (THz) radiation is used today most prominently for security screening at the airport. It’s the machine you stand in with your hands up as it swings its scanning arms in front and behind you. In medicine, terahertz imaging has the potential to help diagnoze certain types of cancer and to monitor a variety of health parameters to aid in assessment of overall health. Because of the extremely short length of terahertz waves, this imaging modality has a lot of limitations, including shallow penetration into tissues, and that prevents it from being used more widely. Yet, since it’s non-ionising, it’s probably safe and may even replace dangerous X-rays for some applications.
Currently, terahertz imaging is very poor at scanning curved surfaces even though it can peer a few millimeters deep into some tissues. To overcome this, researchers at Tokyo Institute of Technology have developed a flexible and even wearable terahertz scanner that can image curved 3D surfaces such as our skin.
