开发了一种非侵入性、实时监测设备的原型，用于检测继发于疾病或损伤（如脑出血（ICH））的大脑变化。最终的目标是一种非侵入性的、真实的时间传感器，它可以提醒临床医生昏迷病人的大脑因出血、癫痫发作或中风而发生的变化。在这项工作中，400 MHz的电磁（EM）信号发射的天线（T），入射到一个“脑凝胶”在体外ICH模型，并接收（R）天线。发现接收信号的变化是由血液的存在引起的。发现接收功率（PR）是血液横截面积的线性函数，如垂直于入射波测量的。此外，该传感器能够在1000 mL体外模型中检测到低至1 mL的血液。
A prototype for a non-invasive, real-time, monitoring device was developed to detect changes in the brain secondary to disease or injury such as intracerebral hemorrhage (ICH). The eventual goal is a non-invasive, real time sensor that can alert the clinician to alterations in the comatose patient’s brain resulting from hemorrhage, seizure or stroke. In this work, a 400 MHz electromagnetic (EM) signal was transmitted with an antenna (T), incident on a ‘brain gel’ in vitro ICH model, and received by a receiving (R) antenna. Changes in the received signal were found to be induced by the presence of blood. The received power (PR) was found to be a linear function of the cross sectional area of blood, as measured normal to the incident wave. In addition, the sensor was able to detect as little as 1 mL of blood in this 1000 mL in vitro model.
