Smart Metal Artifact Reduction (MAR)
Our innovative, projection-based method delivers exceptional CT image quality.
MAR is designed to reveal anatomic details obscured by metal artifacts, helping clinicians utilize CT scans, diagnose disease and contour targets with greater confidence.
Based on the latest in GE Healthcare smart technology, MAR uses an automated, three-stage projection based process to help improve the quality of CT data within the projection space, rather than in image space. This innovative, projection-based method helps to reduce photon starvation, beam hardening and streak artifacts caused by metal in the body, such as hip implants, spine screws and dental fillings.
MAR offers the following benefits:
MAR uses a three-stage, projection-based process to help deliver consistent, enhanced image quality that addresses both beam hardening and photon starvation artifacts.
MAR requires just a single scan to create an exceptionally clear image, helping you to deliver dose conscious care.
Streamlined workflow for patient comfort.
The efficient, single-scan process helps to keep patient time inside the scanner short.
MAR is designed to enhance clarity across a range of cases with metal including scans with hip implants, dental fillings, screws or other metal in the body.
Our metal artifact correction technology uses an automated, three-stage projection based process to help improve the quality of CT data within the projection space, rather than in image space. This projection space correction leads to images that are consistent with the uncorrected image and of exceptional image quality.
Stage One: Corrupted samples in the projection that correspond to metallic objects are identified.
Stage Two: Inpainted data is generated by replacing the metal corrupted projections with the corrected data. The corrected data is generated using the forward projection of the classified image.
Stage Three: The final corrected projection is generated using a combination of the original projection data and the inpainted projection, revealing anatomic details hidden beneath the artifacts.
