Future of Engineering

Researchers at Georgia Tech have developed a new, single-exposure imaging tool that allows quick and unobtrusive scanning of tissues. This device resembles palm sized medical scanners known as "tricorders" in the Star Trek science-fiction universe.





This portable tool uses a narrowband filter mosaic which includes photosensitive pixel sensors that observe different wavelengths, allowing for multispectral imaging. This portable tool helps in early detection of erythema, bruises and pressure ulcers that develop in people with impaired mobility and sensation.

“Although multispectral imaging has matured into a technology with applications in many fields, clinicians and practitioners in these fields have generally stayed away from it due to extremely high costs and lack of portability,” said Dr. Stephen Sprigle, director of CATEA and professor of industrial design and human physiology. “Now, the possibilities are plentiful.”

The CATEA (Georgia Tech’s Center for Assistive Technology and Environmental Access) researchers have filed for a patent and are currently looking for financial funding to launch a commercial version of the device.
