CIRS Launches New MRI Distortion Check Software


MRI Distortion Check is a new, cloud-based solution designed to quickly and automatically quantify distortion in MRI images. Used in conjunction with CIRS MRI Grid phantoms, the software provides the capability to quickly and accurately measure distortion throughout the entire image volume.

After automatically detecting thousands of grid intersections, the software registers either a CAD or CT scan ground truth to these MR detected control points. An interpolation is then performed to generate 3D distortion vector fields.

Results can be reported in a variety of output formats including scatter plots, contour plots, box and whisker plots and DICOM overlays that can be imported to TPS or other third-party software. The software algorithms will work with any grid configuration and CIRS employs proprietary 3D printing techniques that enable easy modification of grid phantoms to meet customer requirements.

“With this new and innovative solution to measuring MR distortion, we are excited to present our customers with a seamless, efficient workflow starting from phantom setup through image acquisition and detailed analysis. Results and trends can be monitored by machine, MR sequence, phantom or any combination of the same,” states CIRS President Mark Devlin.
