High Sensitivity 2MHz TCD Doppler Sensor for Craniocervical Junction

Product Description

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.

WorkMode:

2M (pulse); the 4M (pulse) mode; 4M (continuous) mode; hardware each time only one way to work.

Wins: the number of windows.

Also that depth number. The new hardware to a maximum depth of 4. Can make four spectral windows, each spectrum window that is a depth of sampling volume window.

Hardware every two adjacent sample volume of nearly half of the window is a signal overlap. Example: the first depth signal also contains a a half second depth signal, and the first depth signal also contains half of the first depth signal, also contains the signal of the half 3 depth, but the depth a signal is not the first depth signal. Nos. 1 and 3 of the depth of the signal is completely independent, the first 2 and 4 of the depth of the signal is also completely independent. When such a depth of four signal displayed on the visual feeling there will be a transition.
