VOLTAGE-SPACE ANALYSIS OF AUDITORY BRAINSTEM RESPONSE

这项研究的目标是设计自动化的方法来分析 听性脑干反应(ABR) 正交通道。 生成的3通道李萨如轨迹(3-CLT)显示线性和 平面部分，将使用经过测试的算法进行检测 背景噪音的真实条件。 3-CLT方法可能对病理更敏感 听觉神经系统的变化比ABR更大，尽管ABR有 在听力学和神经学中被广泛用于脑干的测量 正常或不正常。 自动化方法将设计用于微型计算机，很可能是 作为未来诱发反应记录系统的基础。在… 现在至少有六家公司生产这种系统，主要用于临床， 但ABR系统目前无法记录或分析3-CLT，并且 可靠的算法还不为人所知，因为它本来就很复杂 3-CLT所需的耗时分析。

The goal of this research is to devise automated methods of analyzing the Auditory Brainstem Response (ABR) when it is recorded using three orthogonal channels. The resulting 3-Channel Lissajous Trajectory (3-CLT) shows both linear and planar portions, which will be detected using algorithms tested under realistic conditions of background noise. The 3-CLT methodology is likely to be more sensitive to pathological changes in the auditory nervous system than is the ABR, though the ABR has had extensive use in audiology and neurology as a measure of brainstem normality or abnormality. The automated methods will be designed for microcomputers which are likely to be the basis for evoked response recording systems in the future. At least six companies now produce such systems, primarily for clinical use, but the ABR systems cannot record or analyze the 3-CLT at present, and reliable algorithms are not yet known for the otherwise complex and time-consuming analysis that the 3-CLT requires.
