Intelligent Adaptive Wireless Reconfigurable EEG

描述（由申请人提供）该提案的总体目标是使用创新的无线脑电图系统改善动态和长期脑电图监测。本提案的具体目标是开发一种具有实时自适应和重新配置能力的动态无线脑电图监测系统，该系统将允许在相同的带宽和小型便携式封装中传输更多的临床数据。拟议的设备将使其数据采集硬件适应潜在的临床事件，使其能够将其高传输速率集中在临床相关事件期间。事件将被我们强大的癫痫监测算法检测到，该算法将直接控制灵活和创新的硬件。其结果是增强的无线脑电图在一个小的封装，低功耗和数据质量可与笨重的临床系绳系统相媲美。由于新的FDA遥测指南限制了医疗设备中频率和带宽的可用性，因此优化带宽的能力是及时的。优化输出的另一个好处是，可以在没有过大数据文件的情况下创建更有意义的数据，这将加快分析和审查的速度。最后，所提出的设备将能够实时动态地重新配置自身，以补偿严重的数据损坏事件，例如当一个或几个电极松动或分离时。综上所述，两大创新是：1-实时自适应能力，可调整采集和传输的脑电图数据的数量和质量，以更好地反映潜在的临床事件（如癫痫发作）；2-通过脑电图采集系统的实时自动重构，实现更实用、更准确的门诊监测。

DESCRIPTION (provided by the applicant) The overall goal of the proposal is to improve ambulatory and long-term EEG monitoring using an innovative wireless EEG system. The specific aim of this proposal is to develop an ambulatory wireless EEG monitoring system with real-time adaptive and re-configuration capabilities, which will allow more clinical data to be transmitted in the same bandwidth and in a small portable package. The proposed device will adapt its data acquisition hardware to the underlying clinical event permitting it to focus its high transmission rates to periods of clinically relevant events. The events will be detected by our powerful seizure monitor algorithm which will have direct control over a flexible and innovative hardware. The result is enhanced wireless EEG in a small package, low power and with data quality comparable to bulkier clinical tethered system. The ability to optimize bandwidth is timely due to new FDA telemetry guidelines, which restricts the availability of frequencies and bandwidths in medical devices. Another advantage to optimizing output is that more meaningful data can be created without excessively large data files, which will speed analysis and review. Finally, the proposed device will be able to dynamically reconfigure itself in real time to compensate for serious data-corrupting events such as when one or several electrodes become loose or detached. In summary, the two major innovations are: 1- Real-time adaptive capability for adjusting the quantity and quality of the acquired and transmitted EEG data to better reflect the underlying clinical event (such as a seizure), 2- more practical and accurate ambulatory monitoring by the real-time automatic reconfiguration of the EEG acquisition system. In Phase I, we designed, fabricated and tested a prototype system. Bench top and clinical testing showed that the system can indeed modify its output in response to artifacts or changes in EEG morphology. In Phase II, we will complete development including a radio design that meets the new FDA guidelines, and test on long-term patients with epilepsy.
