Neuroimaging Software Solutions

Our research and software development focus on monitoring neurological diseases, planning neurosurgical interventions, supporting clinical trials and performing quantitative studies.
Efficiency, reliability and accuracy of software assistants for evaluating neuroimaging data is of paramount importance within clinical settings, where planning results or therapy decisions might depend on individual measurements.
Diseases like brain tumors, arteriovenous malformations, multiple sclerosis or Alzheimer are only a small subset where our qualitative and quantitative neuroimaging techniques have already proven useful.

Competences

Neurological Monitoring

We provide advanced image analysis techniques required for a variety of neurological questions: fiber tracking, quantification of diffusion MRI data, volumetric brain analysis, ventricle volumetry, cortical thickness measurement, lesion segmentation and analysis of lesion correspondence.

Neurosurgical planning

Neurosurgical intervention planning demands for a precise and efficient reconstruction and visualization of the tumor and the risk structures like vessels, axonal fibers and functional areas. Based on multimodal MRI data we developed solutions for computing risk structures by fiber tracking, fMRI visualization and multi-modal vessel extraction.

Diffusion MRI

We provide solutions for efficient fiber tracking, clustering, uncertainty analysis, and fiber visualizations. While our algorithms can also rely on clinically established diffusion models like tensors, our fiber tracking algorithms are still able to reconstruct difficult constellations like fiber crossings.
