Laser Speckle Tissue Blood Flow Imager OMEGAZONE Hemodynamics Measurement by Laser

OMEAGZONE is the instrument to obtain the colored blood flow image in high resolution of living tissue non-invasively and continuously. Every measurement point is captured by the pixel of the CCD, or CMOS camera simultaneously, therefore, there is no time lug between the all points, and the each blood flow value can be compared.

There are two models. One is OZ-2 with the black & white CMOS, or CCD camera, and the other is OZ-3 with a black & white CMOS (or CCD) + color CMOS (or CCD) in one camera. OZ-3 shows color real images continuously, and it is possible to the compare the color difference between real images and the blood flow images.
The lens can be changed to adapt the measurement size. The size is about from about 1 cm square to 40 cm square.
Two kinds of software, for measurement and for analysis, are installed in the computer-based image processor, and it is easy to analyze the saved images after the measurement.
The measurement software has three mode, and the measurement image number per second and the resolutions are described below.

High Resolution mode(Hi-Res)
OZ-3 : 1 image/sec、image resolution 750 x 560
OZ-2 : 2 images/sec, image resolution 639×480
High Speed mode (Hi-Speed)
OZ-3 : 15 image/sec、image resolution 250 x 186
OZ-2 : 15 images/sec, image resolution 91×68
High Speed AVG (HS -AVG)
OZ-3 : image resolution 250 x 186
OZ-2 : image resolution 91×68 3

Also, OZ-2 Pro model has EMA mode ( exponential moving average), and it shows about 30 images / sec in 639×480.

Features

  1. High resolution
  2. High speed
  3. Measurement and Analysis software
  4. Wide range of measurement by changing lens
  5. Center of measurement area is pointed by red laser light (OZ-2 mini & LCB excepted).
  6. Optical zero null function eliminates light from outside.
  7. Blood Flow data is saved as Excel files.
  8. OZ-2 shows Real Color Images with Blood Flow Images continuously and simultaneously.
  9. OZ-2 Pro model can show pulsatile blood flow of human.
  10. OZ-2 mini model is suitable to set up on a small dable.

Models

OZ-3 NEW MODEL

New OMEGAZONE, OZ-3, shows Color Images by room light, Black & White Images by laser light and Blood Flow Images calculated from the B&W Images.
It is possible to know the detail condition of living tissue by comparing Blood Flow Images with Color Images.
The three images synchronize and are displayed, and saved simultaneously.
The measurement area can be changed by using different lens.
