VesselMap
Static Vessel Analysis Software
Using the unique analysis software VesselMap, vascular parameters are determined and analyzed from previously acquired retinal images. These parameters are valid biomarkers and therefore risk factors or prognostic indicators for vascular diseases and vascular events. Our VesselMap is excellently suited for use in clinical routine as well as for medical research and provides important information about the individual vascular risk of patients, e.g. for:
- Risk assessment of vascular-related diseases
- Estimation and prediction of progression
- Testing of therapeutical approaches
- Monitoring the course of therapy
- Motivation of patients through early progress monitoring
Further information: Method of Static Vessel Analysis
- Simple, software-guided application
- Automatic determination of vessel topology with preselection of vessel sections as well as precise determination of vessel parameters
- Integrated function for progress monitoring for a significant improvement in reproducibility and fully automatic evaluation of follow-up images
- Available with German and English user interface
- At least one image of the retina is acquired in a standardized manner with the imaging system
- The evaluation of the digitized fundus image is performed using ring-shaped markers centered to the location of the optic disc
- The software makes an automatic preselection of all detected arterial and venous vessels
- From this, the vessel diameter is automatically averaged spatially-segment-wise for each marked vessel
- In the last step, the vascular parameters are calculated according to the procedures described by Hubbard in the ARIC study [1][2].

VesselMap determines the following static vessel parameters:
- Central retinal arteriolar equivalent (CRAE): arterial model vessel diameter.
- Central retinal venular equivalent (CRVE): venous model vessel diameter.
- Arteriolar-to-venular ratio (AVR): the CRAE/CRVE ratio.
The central equivalents CRAE and CRVE describe model vessel diameters for characterization of the central vessels. These biomarkers take into account all arterial and venous vessels flowing into the retina according to a geometric-hemodynamic weighting.
VesselMap is available as a software license in combination with different click packages (200, 300 and 500 measurements) and terms (1 year and 3 years). It can be combined with various imaging systems from leading manufacturers and integrated into the existing clinical environment. For this purpose, the analysis and calculation parameters of the software are adjusted to your system and adapted accordingly.
In order to integrate the software into your existing practice environment, a suitable fundus camera and computer must be available. We will be happy to check the compatibility of your existing hardware with our products. Alternatively, both can be obtained from Imedos.
- The imaging unit, for acquiring the fundus images if a suitable system is not yet available.
- The workstation consisting of instrument table, computer unit and power supply for comfortable and mobile work.
- The server solution, for connecting different workstations and synchronizing the corresponding databases.
- The practice system connection, for smooth integration of static vessel analysis into everyday practice. (DICOM)
- The research option, for unrestricted measurement of vessel diameters outside the standardized examination protocol.
