Performance Advantages
1. acquire the blood flow images in real time with micrometer resolution, and advance the accuracy of the blood flow value by correcting the interference of static scattering or multi-scattering
2. Analyze the blood flow mean value of the region of interest(ROI) and vessel diameter value online or offline, and analyze the blood flow mean value and standard deviation of the time of interest(TOI) offline, moreover, any shape and quantity of ROIs could be drawed, and the position and size of any ROI could be adjusted freely
3. The blood flow imaging speed could be achieve 60 fps even though in the condition of maximum pixels
4. The optical magnification could be read directly without calculation
5. Multi-format could be choosed for recording, like raw data/.jpg/.bmp/.png /.avi and so on
6. When record images, you could choose to image continuously or with a specific interval
7. A excellent system stabilization could be achieved based on high-coherence laser illuminating and high-performance 12-bit camera acquiring
8. A whole acquiring and analyzing plan and sale-service could be offered
