CT metal artifact reduction
The Metal Deletion Technique (MDT) for CT metal artifact reduction improves image quality in 86% of cases, and improves diagnosis in 14% of cases. This includes cases of cancer and stroke that were missed without MDT. MDT reduces metal artifacts due to beam hardening, motion, scatter, and photon starvation. Many competing techniques only reduce beam hardening artifacts. The MDT software works with images from any manufacturer's scanner, and can be integrated with PACS. MDT produces better results than metal artifact reduction products from GE, Siemens, and Philips, according to an independent research group. It is currently used in more than 140 hospitals around the world, including MGH, MD Anderson, Stanford, UCLA, and University of Cambridge.
Commercial licensing terms are available upon request. CT scanner manufacturers or radiology software vendors can integrate MDT into their products. MDT can also be used for research applications. First, review the software manual. Next, email a description of your planned application to firstname.lastname@example.org.

|Examples (before and after metal artifact reduction)|
|Bilateral hip replacements (with streaks obscuring perirectal lymphadenopathy from rectal cancer)|
|Aneurysm clip (with streaks obscuring an acute hemorrhage)|
|Bilateral hip replacements (with streaks obscuring a fluid collection adjacent to the joint)|

MDT is not FDA approved, and is only intended for research use. It is covered by US patent 8233586.
