| Research Abstract |
The simpler and earlier abnormality detection system was developed by applying the SST(Singular Spectrum Transform) for the Real-time diagnosis and prediction of active equipment. The movie-prediction method was developed to predict the near future of the medical X-ray movie by applying the PCA(Principle Component Analysis) and SSA(Singular Spectrum Analysis). The imitation tumor was moved with the XYZ-stage and its motion captured with the CCD cameras was successfully predicted by SSA method with the 1mm accuracy of 95% reliability.
