| 摘 要： | 诱发电位的实时监测在临床中有重要意义。本文提出利用多分辨率子波分析技术来实时监测视觉诱发电位的潜伏期。为克服随机噪声的影响，我们引入相邻响应的相关系数来修正所检测得的潜伏期的偏移，并应用前一次响应的波峰位置来决定当前的搜寻范围。实验表明，本方法能实时监测视觉诱发电位的潜伏期。

| Abstract: | It is important to make real_time monitor of evoked potentials in clinical usage.In this paper,we use multiresolution wavelet decomposition to track the latency of the visual evoked potentials.We also make use of the correlation coefficient to revise the shift of latency.In searching the peak location,we use an automated step,which is based on the preceding peak,for more detailed searching.Experimental results show that it is possible carry out the real_time to track for the latency of visual evoked potentials in this method. |
