Atherosclerosis is the main cause of ischemic stroke. It occurs as a condition that leads to thickening arterial blood vessel walls and narrowing vessels, which can seriously affect normal flow blood. Currently, detection stenosis relies on large-scale hospital equipment like computed tomography (CT) magnetic resonance imaging (MRI), require specialized technicians operate are not convenient for daily use. In addition, affects multiple parameters hemodynamics in field, relying single physical quantity sufficient understand field localized stenotic vessel. Here, we demonstrated combined sensors pulse wave velocity (CSPB) based photoelectric plethysmography an ultrasonic Doppler device. We found when rate increased by 30%, amplitude difference curve between two sides over 11%, decreased 8%, resistance 11%. also prepared silicone-based models vessels build vitro systems achieve more accurate simulation vascular diseases. Based this, studied curves CSPB under different parameters. Meanwhile, used finite element analysis method fluid-structure interactions study changes conditions. This expected provide theoretical technical references achieving noninvasive cardiovascular cerebrovascular diseases multisensor fusion.
