Georgia Institute of Technology researchers said their new single-exposure imaging tool could significantly improve multispectral imaging -- a technology that enables subsurface characterization. The scientists say the filter can be used by 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, the scientists said the technology could potentially offer a reliable, low-cost method to instantaneously classify military targets, sort produce, inspect product quality in manufacturing, detect food contamination and diagnose early stage cancer and tumors.

The system was developed at Georgia Tech's Center for Assistive Technology and Environmental Access as part of a project to design a portable erythema and bruise-detection system to enhance early prevention and diagnosis of pressure ulcers -- a secondary complication for people with impaired mobility and sensation.
