Spectrum Endoscope System

Considered as one of the most widely used medical instrument, electronic endoscope has become a powerful tool in cancer diagnosis and treatment. However, conventional endoscope that works in direct observation mode is difficult to distinguish tissue with potential cancer from normal tissue. To solve this problem, we developed a spectrum endoscope. This system uses the principle that different wavelength of light could strengthen the differences in physiological characteristics of tissue, which could be reflected by means of images. This spectrum endoscope system has not only all features of conventional endoscope system, but also the diagnostic capacity using the specific wavelength for observation. The system can also conduct spectrum estimation using Weiner estimation method. In the design of the system, several critical means were used to accelerate the imaging processing speed. The imaging results show that this spectrum endoscope system has a better image compared to the conventional endoscope.
