| Abstract: |
| This paper introduced a development of softw are used for auto-checking and analyzing a change of the cerebral blood flow dynamics by the way of admittance. ［Method］In order to attain above the purpose, the authors combined computer technique and bioelectric technique, and then rea -process biologic signal collected ΔＹＬ,ΔＹＲ,ECG,etc.by computer. ［Results］ The removing noise, autom atically picking up characteristic point, cerebral admittance plethysmogram,cerebral admittance differential loop, admittance spectral analysis and computing twenty-seven parameters of cerebral blood variety were provided with this program . ［Conclusion］ This kind of program design may be provided with developing medical academic study and clinical detecting instruments |
