CAAS 4D Flow

Complete assessment of your MR 4D Flow data

Caas MR 4D Flow is specifically designed to extract relevant information from 3D phase-contrast (PC) MR images, within a few clicks.

 

Based on these phase-contrast images, two pioneering 4D Flow modules are offered to perform a complete flow analysis that can aid in reading and interpreting cardiovascular MR images and assist in planning the time and type of an intervention.

 

These two modules include a module to analyse vessels, from the aorta up to smaller vessels in for example the kidneys (Caas MR 4D Artery), and a module to analyse the heart valves in terms of regurgitation fraction (Caas MR 4D Heart).

Key Results:

  • Visualization of aortic blood flow as streamlines, pathlines and color-coded vectors

  • Distribution of wall shear stress and local values of wall shear stress

  • Pressure difference over a segment

  • Visualization and quantification of regurgitant fraction over all four valves

  • 2D flow phase-contract analysis

Key product features

  • Intracardiac analysis with automated valve tracking

  • Visualization and quantification of blood flow in just a few clicks

  • Load and analyze 4D flow datasets from all main OEM vendors
