Our sense of vision tells us much of what we know about the world around us; yet the human eye is only capable of sensing a very narrow spectrum of the light it receives, in wavelengths from about 400 to 700 nm. Current research being conducted at the Vis Center is investigating the possibility that broadening the range of imaged light could greatly improve a surgeon’s ability to identify anatomical features in minimally invasive surgery, adding visual cues not even available during open surgery.
Recently at the Emerging Technology Session of the 2010 World Congress of Endoscopic Surgery hosted by the Society of American Gastrointestinal and Endoscopic Surgeons Matt Field, Vis Center Software Engineer, presented a poster describing a new research initiative into multi-spectral imaging. Entitled “Assessment of Multi-Spectral Imaging for Enhanced Visualization in Minimally Invasive Surgery”, the poster described early results from research with tissue samples.
The future application of this research will be to incorporate the findings of the experimental system into a prototype multi-spectral endoscope. An LED-based endoscopic light source will be modified to include these new light spectra. As this work is at a very early stage, testing will continue to conclusively determine the best possibilities for image enhancement.
