摘　　要：超声经颅多普勒血流分析仪是利用颅骨薄弱部位作为检测的声窗,用多普勒频移效应研究脑底动脉主干血流的一种无创性的检查设备,目前临床应用非常广泛。为了保证超声经颅多普勒血流分析仪的性能可靠,对其进行计量校准就显得尤为重要。基于此,本文研究了一套超声经颅多普勒血流分析仪的检测装置。实际应用表明此检测系统能较客观地评估超声经颅多普勒血流分析仪的性能,可以作为检测(校准)的装置。Ultrasound transcranial Doppler blood flow analyzer is a noninvasive device to study the main blood flow of the basilar artery by using the Doppler frequency shift effect and using the weak parts of the skull as the acoustic window. In order to ensure the reliable performance of ultrasound transcranial Doppler blood flow analyzer,it is very important to calibrate it. Based on this,this paper studies a set of ultrasound transcranial Doppler blood flow analyzer detection device. The practical application shows that this detection system can objectively evaluate the performance of ultrasound transcranial Doppler blood flow analyzer,and can be used as a detection(calibration)device.
