Abstract

2-D signal processing is proposed for use in automated evoked-potential (EP) systems in order to reduce data-acquisition time and eliminate the effects of artifacts. Sequential EP recordings are organized in a 2-D data array and filtered in the frequency domain using 2-D Fourier techniques. Examples of auditory brainstem response (ABR) processing for intraoperative monitoring and latency-intensity function determination are given to illustrate two applications. The results show clearly that 2-D filtering can enhance the signal characteristics. This method, when applied as a latency tracking technique, can immediately be used in ABR diagnostic screening to determine audiological thresholds and to rule out neurological abnormalities. 2-D filtering has the potential to reduce such a testing process to 5-10 minutes.
