Researchers at the Institute of Technology Georgia have a narrowband filter mosaic that the use and functionality of technology multi-spectral imaging, which aims to extend a welcome touch. The new imaging single exposure could significantly improve point of care tools for medical imaging and forensic recognized by empowering doctors before without specialized training, and evaluate, in real time the severity of bruises and erythema, regardless of skin pigmentation of the patient or lighting available.

In addition to this application, the filter can potentially provide reliabile, low cost method to produce immediately classify military targets, sort control, quality of products in production to detect contamination in food, leading Mining remote sensing, monitoring of atmospheric composition in environmental engineering and diagnose early stage cancer and tumors.

The technology was developed at Georgia Tech Center for Assistive Technology and Environmental Access (CATEA) as part of a project with a portable erythema and bruise detection technology that will improve early diagnosis and prevention pressure ulcers, a secondary complication for people with developmental design decreased mobility and sensation.

Currently, clinical assessment of bruises is subjective and unreliable, especially when they encounter people with dark skin pigmentation. Improved imaging can lead to earlier intervention which is suspected of physical abuse of crucial importance. Similarly, early detection of erythema can trigger preventive, this transition can stop the slough.

Pressure ulcers are serious complications for people with limited mobility and sensation. The annual expenditure for Medicare is cautiously estimated at 1.34 billion dollars for the treatment of pressure ulcers. Early detection of erythema can prevent progression to more severe stage III or stage IV pressure ulcer.

The mosaic filter can be conveniently laminated with imaging sensors used in digital cameras. With a patent pending, CATEA researchers are currently seeking cooperation or assistance in the development and design of the device.

“Although multi-spectral imaging has become a technology with applications in many fields, clinicians and practitioners in these areas have evolved as a general rule, stayed away from him because of the high cost and lack of portability, “said Dr. Stephen Sprigle, CATEA Director and professor of industrial design and human physiology.” Well, the possibilities are numerous.

A unit of the School of Architecture at Georgia Tech, CATEA access is a center for the promotion of an independent applied research and participation of persons with disabilities through assistance technology and the environment.
