The Volume Graphics GmbH , based in Heidelberg is a developer and manufacturer of software solutions for analysis, visualization and testing of 3D data of industrial computed tomography (CT) in production, quality assurance, science and research.

history

In the early 1990s , the physicists Christof Reinhart, Thomas Günther and Christoph Poliwoda developed a computer system as part of a research project at the Ruprecht-Karls-Universität Heidelberg, which dealt with the visualization of medical image data from computer and magnetic resonance tomography CT scans could visualize three-dimensional volume graphics. The massively parallel computer VIRIM, built in 1995, was the first real-time volume rendering hardware that could render 32 megabytes of data at a frame rate of 20 frames per second (fps) and thus process and visualize CT slice image data sets in real time. Volume Graphics GmbH emerged in 1997 from a project funded by the Federal Ministry of Education and Research. In 1998 the focus shifted from hardware to software; With Vgstudio , the company released the first software product that could analyze and visualize CT slice stacks spatially coherent in all three dimensions on a standard personal computer.

Products

The product family includes Vgstudio, Vgstudio Max, Vginline, Vgmetrology and Myvgl.

Areas of application

The software is based on the data from industrial computed tomography and is primarily used in the manufacturing industry, but also in science and research. Examples are measurement technology on injection-molded and die-cast components or the analysis of composite materials.

industrial production

The software for CT inspection is mainly used in manufacturing industries for:

Science and Research

  • Industrial X-ray CT
  • Medical X-ray CT
  • Synchrotron X-ray tomography
  • Neutron tomography
  • Magnetic resonance imaging

functionality

Inspection of metal casting parts casting (metal)

After scanning, the reconstruction software calculates three-dimensional volume data sets from the projection images. The software recognizes porosities and cavities .

3D printing additive manufacturing

Computed tomography (CT) is used to record complex, additively manufactured components with hidden and hard-to-reach surfaces. Among other things, the software can be used to measure the printed component, compare it with its target model and find defects.

Automated CT inspection

The software carries out quality control throughout the entire production process. From the reconstruction of the CT data to the examination, reporting and manual re-examination. With the help of the OCR functionality ( text recognition ), the software recognizes text and numerical information, on the basis of which automated analyzes are carried out on components.

Inspection of injection molded parts injection molding

The optimal parameter set for the first tool is found through dimensional control of simulation results. After an initial sample test of dimensions and shape, components are qualitatively and quantitatively tested for porosity, inclusions, fiber orientation and volume proportions. In the case of target / actual comparisons, the 3D model of the tomographed injection-molded component is compared with the CAD data of the component. The result is a false color image . The software colors matching component areas green, deviating blue and red, depending on whether the deviation is positive or negative.

Tool offset

The program enables the geometry of manufactured objects or their shapes to be corrected on the basis of CT data of scanned objects or mesh data. As a result, when dimensioning cast parts or their shapes, the necessary allowances, such as. B. for shrinkage, warpage, directional solidification or draft angles can be included iteratively.

Computed tomography reconstruction

In CT reconstruction, 2D x-ray images that can be generated using different x-ray imaging methods are merged into a 3D data set. On the basis of the resulting 3D component representation, statements can be made about the external and internal structures of a component as well as its material properties.

Micromechanics simulation

The software uses an immersed boundary method for microscale simulation of stress distributions directly on CT scans. Virtual strength tests can thus be carried out on complex material structures without the need for volume networking.
