The detection frequency range after opt-electric converter is 120 KHz and it is about 5 times of that of the FLO-C1, and the operating frequency range can be set from 5 KHz to 120 KHz. Therefore, the OMEGAFLO-Lab can be used for both slow speed blood flow and fast speed blood flow.
The characteristic of the raw signal after the opt-electric converter can be seen by FFT (Fast Fourier Transform) on the computer display, and the frequency range for operating blood flow value can be set by confirming the frequency characteristic of the blood flow under study. The OMEGAFLO-Lab uses a laser diode having the wavelength hardly affected by the difference of absorption due to the oxy ?? deoxy condition of erythrocytes. The measurement depth is about 1 mm from tissue surface.
The OMEGAFLO-Lab is used for measuring brain, skin, internal organs by using conventional optical fiber probes.
The OMEGAFLO-Lab operates blood flow value, and also display and saving data simultaneously. Therefore, additional data acquisition is not needed.
The 2ch-FLO-Lab is used for blood flow comparisom between in normal position and in region of interest.
The new software , FMV version, showing blood flow(FLOW), blood volume (MASS) and blood flw velocity(VEL.) can be installed.
The frequency range of the forearm skin is under 20 KHz, but that of the finger skin is about 100 KHz.
Operating frequency range can be set after confirming the frequency characteristics.
