Portable Tool Makes Images of Bruises and Tumors

Clinicians who use the device would be able to detect and evaluate how bad bruises and erythema are in real time, which can sometimes be a challenge in patients who have darker skin pigmentation. Better imaging will offer earlier detection of erythema, which could help stop the progression of pressure ulcers. It also has implications for earlier intervention in suspected cases of physical abuse.The wallet-sized device has a filter that works at four or more wavelengths from visual to infrared, with 20-nm bandwidth in a single exposure. It can be laminated with the same imaging sensors that are used in digital cameras.The researchers are looking for collaborators and funding to continue developing the device.
