Abstract
Narrow Band Imaging (NBI) is an optical medical imaging technique that utilizes narrow band light to enhance the visualization of mucosa and tissues. NBI has been used to enhance traditional white light endoscopic imaging. A key feature of NBI is its ability to provide high-contrast images of blood vessels in tissues, especially compared to white light. For instance, in gastrointestinal cancer detection, specific narrow-band light such as green light, which is strongly absorbed by hemoglobin in the blood, is used to improve the visualization of blood vessels, aiding physicians in more precise diagnosis and evaluation. NBI can achieve multi-spectral imaging by using various colored lights for illumination or optical filters in white light endoscopes. In this study, we have developed a low-cost NBI multi-spectral system. The NBI system is built with multi-color LEDs into a handheld probe. The system was evaluated on oral mucosa and pigmented mole, demonstrating its promising potential in identifying and classifying pathological changes in epithelial tissues.
