VEDDAC volume
Digital volume correlation - VEDDAC volume (available June 2020)
Software for measuring structural changes inside materials.

VEDDAC volume offers the possibility to use digital volume correlation to detect deformations and changes in the inside of materials completely and non-destructively. The VEDDAC volume software is based on 3D volume correlation (DVC - digital volume correlation) of x-ray data. The measurement information consists of spacial displacement and strain fields inside the object.

Intelligent analysis technology

With VEDDAC volume it is possible to compare two loading conditions of a material. In addition to our standard volume correlation, an algorithm for highly noisy data is also available. A new high-precision subpixel algorithm has been developed to determine the smallest displacements and strains.

This makes VEDDAC volume the preferable evaluation tool for x-ray computed tomography (CT) or magnetic resonance imaging (MRI).

Extensive visualization features

With our new 3D visualization you can easily visualize your correlation results impressively. 3D sectional images and semi-transparent 3D illustrations allow users to locate and highlight even the smallest material changes. VEDDAC volume is an essential tool for the early detection of material failure.


You can use VEDDAC volume in a wide variety of areas:

  • Materials science
  • Microsystems technology
  • Product testing in various industries, e.g. pharmaceutical, food and building materials industries
  • Medical and sports sciences
  • Power engineering
  • and more
