| Research Abstract |
Relation between brain viability and OCT signal has been investigated. Keeping the tissue temperature after overdose of anesthetizer, the OCT signal has increased before cardiac arrest (CA). For periodical changes of temperature, the negative correlation relation between OCT signal and temperature was shown. There is no influence of anesthetizers for increase of OCT signal. Under the diffuse reflection measurement, the relative increase of 1.2μm light was measured through CA to show the reduction of CcO. In defuse optical measurements from 0.5μm to 0.9μm using slices of brain, the increase of absorption coefficient and the decrease of scattering coefficient were measured. Further researches are necessary for applications.
