A new non-invasive cerebral blood flow monitoring system based on inductive sensing technology

Timely reperfusion and revascularization of ischemic tissue is the key to acute ischemic stroke treatment. In this paper, a non-invasive cerebral blood flow (CBF) monitoring system is established based on inductive sensing technology. The system was constructed using inductive sensors and LDC1612 evaluation module. Cardiac CBF volume pulsation is monitored by measuring the periodic change in inductive resonance frequency. To examine the performance of the system, conductivity resolution experiments; simulated heartbeat frequency detection experiments and the axial distance change to measured target experiments were performed. Results show that the system introduced in this paper can effectively detect the cardiogenic pulsation of CBF volume, which is expected to break the time window effect caused by imaging examinations and provide a new bedside real-time technology for CBF perfusion monitoring.
