Carbon nanotubes for X-rays
US researchers from the University of North Carolina have found a surprising and interesting application for CNT-based field emission cathode. They say it can be used for X-ray radiation suitable for medical diagnostics.
The North Carolina team and researchers from Applied Nanotechnologies have generated X-rays using a room temperature array of CNTs. The nanotubes are used to create the electrons and provide a sufficient X-ray flux for medical imaging.
According to the research team, the device is smaller and cooler than previous designs and its X-ray pulses are more focused. The response time of the generator is also smaller than previous models, and the pulse shape can be programmed to help track moving objects.
Professor Otto Zhou, director of the North Carolina Centre for Nanoscale Materials, says that it will take two or three years to fully develop the technology. New X-ray tubes can be supposedly used in medical and industrial applications.
