CIRS Launches New MRI Distortion Check Software

September 6, 2017 — MRI Distortion Check is a new, cloud-based solution designed to quickly and automatically quantify distortion in magnetic resonance images (MRI). Used in conjunction with CIRS MRI Grid phantoms, the software provides the capability to quickly and accurately measure distortion through out the entire image volume.

After automatically detecting thousands of grid intersections, the software registers either a computer-aided detection (CAD) or computed tomography (CT) scan ground truth to these MR-detected control points. An interpolation is then performed to generate 3-D 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 treatment planning systems (TPS) or other third-party software. The software algorithms will work with any grid configuration, and CIRS employs proprietary 3-D printing techniques that enable easy modification of grid phantoms to meet customer requirements.

CIRS will display the MRI Distortion Check Software, along with the Model 604 Large Field MRI Distortion Phantom, and 603A MRI Skull Distortion Phantom, at the 2017 American Society for Radiation Oncology (ASTRO) annual meeting, Sept. 24-27 in San Diego.
