MR diffusion tensor imaging (DT-MRI) is a new technology which reflects the direction of molecule diffusion better than traditional diffusion weighted imaging (DWI) does. DT-MRI has great advantages of showing the distribution of white matter fiber path and its spatial structures because the water molecules in brain white matters have the obvious(More)
A 40 Hz event related potential(ERP) detecting system is introduced here. The system employs the elliptic--type filters which have excellent edge features to extract signals of narrow-band frequency. It exploits the correlation--threshold method proposed by us to cancel the muscle artifacts. We also realizes the automatic control of experiment procedure and(More)
This study was aimed to find some parameters for characterizing the modulation transfer function (MTF) specific to diagnosing eye diseases. Least-square regression method was used for MTF curve (at logarithmic axis) fitting with quadratic equation so as or cubic equation to obtain the desired parameters. The data of normal and some eye diseases were fitted(More)
