Sectra CT-based Micromotion Analysis (CTMA)
Sectra’s CT-based Micromotion Analysis (CTMA) simplifies and speeds up the process of validating new orthopaedic implants in Vivo. CTMA uses CT images taken at different time intervals or weight bearing vs non weight bearing to measure 3D motion of an implant or bone fragment on a sub-millimeter scale. Already after six months this information provides the surgeon and implant manufacturers with a strong predictor of the long-term survival of the implant.
Precision On a submillimeter scale 
Speed up Fast validating of new implants 
Efficient User-friendly workflow Implant migration at two years is predictive of the ten-year survival of an implant model. Such migration measurements used to require specialized and expensive RSA labs but can now, with a new technology called Sectra CT-based Micromotion Analysis (CTMA), be done using standard CT's.
Sectra CTMA is the original, patented CT-based RSA solution that eliminates the need for physical markers and a specialized RSA lab. It is rapidly replacing conventional RSA studies because it is more user-friendly, cost-effective, and gives faster results. Making CTMA results highly valuable for FDA approval, post-market follow-up, and providing strong evidence and visualization of implant safety.
CTMA has applications far beyond migration studies and can be used to compare surgical techniques, measure bone fusion, assess screw positioning, and more.
In fact, it is suitable for virtually any part of the anatomy including, the hip, knee, spine, shoulder, elbow, ankle, and wrist.
Furthermore, CTMA is fully compatible with emerging imaging technologies, such as photon-counting CT, and studies have already demonstrated this compatibility.
Sectra CTMA operates as a cloud service, ensuring ease of access and efficient handling of analyses. You can conduct analyses in-house using your own trained and certified personnel.
Alternatively, Sectra offers a full service that includes both the software and the performance of analyses by our specialists. Whether you choose to manage the process internally or leverage Sectra’s expertise, you receive the necessary support and technology to achieve optimal results.
CTMA analyses two CT images by rendering them into 3D models and merging them. The software quantifies the results on a submillimeter scale and provides data on all axes and rotation angles.
When using CTMA in clinical trials, you simply use standard CT imaging. CTMA requires no specialized imaging equipment and is therefore a simple procedure for staff to follow.
30+ peer-reviewed studies have demonstrated the accuracy and reliability of Sectra CTMA. Check out this PDF for the complete list of scientific publications.
