Researchers at Georgia Tech have developed a narrowband filter mosaic that will expand the uses and functionality of multispectral imaging—a technology that enables subsurface characterization. The new, single-exposure imaging tool could significantly improve point-of-care medical and forensic imaging by empowering front line clinicians with no specialized training to detect and assess, in real-time, the severity of bruises and erythema, regardless of patient skin pigmentation or available lighting. In addition to this application, the filter could potentially offer a reliabile, low-cost method to diagnose early stage cancer and tumors.
The technology was developed in Georgia Tech’s Center for Assistive Technology and Environmental Access (CATEA) as part of a project to design a portable erythema and bruise-detection technology that will enhance early prevention and diagnosis of pressure ulcers, a secondary complication for people with impaired mobility and sensation.
