The AVA 5 Microscan Software

MicroScan employs a completely redesigned imaging technology called SDF+ as well greatly enhanced data acquisition and analysis algorithms in the latest version of the MicroScan software application called AVA 5.

The combination of SDF+ and AVA 5 results in the immediate routine use of the microcirculation as an easily monitored parameter in the clinic.

The technology is easy to use, intuitive and fast allowing a nurse to take it on rounds for regular patient checkups. Moreover, it provides reliable, consistent and reproducible data that adheres fully to the rules of the internationally accepted consensus scoring guidelines.

Description of Hardware

MicroVision Medical has a strong focus on high quality imaging, thus allowing for only the best possible images to be presented to the user and the analysis software. Leading the innovations is the age old scientific adagium “garbage in = garbage out”. Therefore the USB3 MicroScan has numerous changes and improvements that allow for superior image quality and highly accurate, reliable and reproducibly image acquisition and analysis.

First and foremost the new SDF+ technology allows the red blood cells to be visualised with greater accuracy and detail, which is essential for enhancing the capabilities of the analysis application. The main innovations of SDF+ are a new form of illumination management and resolution enhancement. The USB3 MicroScan has an increased optical resolution resulting in one pixel recording an area of 0.56 μm2 ! It is this level of detail that allows the USB3 MicroScan achieve superior and leading image quality and analysis accuracy.

The MicroScan Video Microscope System consists of:

  1. Imaging Unit
  2. Calibration Unit
  3. Detachable Handle
  4. Battery Unit (min. 12 hrs usage)
  1. Connecting Video Cable
  2. A/C Adapter
  3. Sterile Disposable Lenses (20 pcs.)

Description of software

MicroVision Medical has worked extensively with intensive care nurses and physicians to deliver the best possible software solution for their needs. Our new AVA 5 has a completely new user interface that includes step-by-step guidance for image acquisition and fully automatic image analysis.

MicroVision Medical has proven that AVA 5 will revolutionise microcirculation monitoring at the bed side. A complete measurement takes less than 5 minutes! This includes the time for an operator to capture images at three sites and the fully automatic analysis.

A real time video of AVA 5 can be viewed here.

  1. Real-time feedback assisted capture (feedback on image illumination, focus and stability) of videos of the microcirculation
  2. Capturing in automatic and manual mode
  3. Analysis within seconds, resulting in automatic segmentation of vessel boundaries with centerline and automatic measurement of analysis parameters like – De Backer Score, Proportion of Perfused Vessels, etc.
  4. Report with analysis results, tables, graphs and images of the segmentation are saved after analysis
  5. Offline analysis of the saved videos (separate purchase)

There is currently no other analysis tool available that can fully automatically analyse microcirculatory images.

Which scores does AVA 4.x generate?
Which scores does AVA 4.x generate?

The scores published in the microcirculatory assessment round table conference meeting:

  • DeBacker Density
  • Vessel Density (total, small, medium, large)
  • Perfused Vessel Density (total, small, medium, large)
  • Proportion of Perfused Vessels (total, small, medium, large)
  • Heterogeneity index
Why does AVA 4.x not include Microvascular flow index (MFI)?
Why does AVA 4.x not include Microvascular flow index (MFI)?

The reason for not including MFI is that it is a more subjective score and has a poor interobserver repeatablity as compared to other flow parameters like PVD and PPV. Please check the related publication here: http://www.ncbi.nlm.nih.gov/pubmed/24885423
