임피던스 방법을 이용한 뇌혈류량 측정기기의 개발(Ⅰ) = Development of Rheoencephalograph(Ⅰ)

다국어 초록 (Multilingual Abstract)

In this study, Rheoencephalography(REG) was designed and constructed. Using the constructed instrument cerebral blood flow(CBF) of left and right brain, CBF change by posture, and reproducibility were studied. Followings are important results.
Relative CBF could be measured noninvasively and continuously. Since reproducibility of the constructed REG was found to be quite high (4 %), the accuracy of the instrument itself was proved. REG can be easily applied for testing the effect of drugs for the patients with cerebral vessel diseases since it is quite sensitive to the relative changes of CBF. Various cerebral diseases can be diagnosed by analyzing the REG waveforms. The area of restricted cerebral blood vessels can be located by arranging the electrode configuration.
Comparative studies with the standard techniques of measuring CBF are needed to verify the accuracy of REG. Further studies on optimal electrode configuration and various artifacts are also necessary.
