【Outline】
OMEGAFLO measures tissue blood flow, blood volume and flow velocity continuously
and non-invasively. It is used for evaluation of the effect of drugs,
transplantations and physiological research.FLO-N1, the non-contact type, can measure- tissue blood flow without contacting the probe on tissue, and it allows measurment and operations on tissue at the same time.The measurement depth- is about 1 mm from the tissue surface. |
|
Non-contact（ＦＬＯ－Ｎ１）
●Blood flow measurement without contacting the
probe Blood flow value is averaged over wider area. Good reproducibility. |
 |
Contact（ＦＬＯ－Ｃ１）
●Conventional laser tissue blood flowmeter
Many kinds of probes are available. Specialized probes can be ordered. |
|
【Theory】
The tissue under study is irradiated by the laser light through the opticalfiber probe, and the light is scattered many times in the tissue.
Some of the photons are scattered by erythrocytes in the tissue, and light does shift in frequency related to the moving velocity of the erythrocytes. Also , the amplitude of the scattered light is propotional to the volume of the e rythrocytes in the tissue. The blood flow signals are obtained from the frequency shift and its amplitude. |
