University of Texas at Dallas researchers have developed a micro imaging device that could be used with an endoscope to spot cancers at an earlier stage. The technology uses LED lighting and hyperspectral imaging to capture near-infrared and ultraviolet wavelengths in addition to the visible light that a conventional camera registers. The Erik Jonsson School of Engineering and Computer Science researchers published a study describing their compact prototype in the May/June issue of the Journal of Medical Imaging. Hyperspectral imaging, originally used in satellite imagery, orbiting telescopes and other applications, goes beyond what the human eye can see as cells are examined under ultraviolet and near-infrared lights at micrometer resolution. The research was supported by National Cancer Institute grants R01CA288379 and R01CA204254, and CPRIT awards RP240289 and RP240542.
