| Research Abstract |
We have made a trial model composed of three-color light emitting diodes (LED) and a miniature charge-coupled device camera for microcirculation imaging. We first confirmed that it clearly captured the microcirculation of pig intestine. We then made a phantom with bovine blood and estimated the oxygen saturation (OS) by Beer-Lambert's law from images under blue LED or green LED. We could estimate OS in some degree and also noticed that modification of the estimation model was needed for better estimation accuracy.
