High Sensitivity 2MHz TCD Doppler Sensor for Craniocervical Junction
Introduction:
The Doppler blood measuring device we developed can equip with 2mhz, 4mhz, 8mhz blood flow sensor to measure the different depth blood flow rate. The output interface is USB port, and input the power is standard PC power. There could offer some sort of raw data or the calculated data as Vp; Vm, Vd, PI, RI, SD, Hr. Besides, we could offer the output as bitmap spectrum when connect with your laptop or PC directly.
The technical requirements stipulate the main technical requirements of the unit pulse wave type (PW) and the dual-wafer separation continuous wave type (CW) ultrasonic Doppler probes, as the basis for technical inspection and evaluation.
