CAAS MR 4D Flow is specifically designed to extract relevant information from 3D phase contrast MR images, within a few clicks. Automatic 3D segmentation of the data provides interactive visualization of flow patterns by means of streamlines, time-resolved path lines and color coded vectors.
Compare different planes in the aorta or different datasets by 2D flow and Wall Shear Stress parameters, provided by the software.

Key Product Features

  • Easy and intuitive workflow
  • Visualization and analysis of flow in the thoracic aorta in just a few clicks
  • Load and analyze 4D flow datasets from all main OEM vendors

In the US, Wall Shear Stress and Pressure Difference analysis are for research use only and not meant for clinical decision support.

Key Results

  • Visualization of Aortic Blood Flow in Streamlines, Pathlines and Color Coded Vectors
  • Distribution of wall shear stress and local values of wall shear stress
  • 2D flow phase contract analysis
