Gastrointestinal cancers remain among the most common forms of cancer. While endoscopy has become a cornerstone of cancer screening and diagnosis over the past two decades, the procedure still misses approximately 8 to 11 percent of tumors, due to visibility limitations. Now, researchers have developed a prototype imaging system that could significantly improve doctors’ ability to detect cancerous tissue during endoscopic procedures.

The new approach, reported in the Journal of Medical Imaging, combines light-emitting diodes (LEDs) with hyperspectral imaging technology to…
