Functional X-ray Analysis
Today the analysis of medical images (X-ray, CT, MRI) is typically concentrating on static characteristics. For example, in order to diagnose a disease of the spine, the disk height, the translational shift of vertebrae or the narrowing of the spinal canal is determined based on medical images.
Due to the lack of feasible tools, it is hardly possible in the daily routine to evaluate further parameters such as, for example, the location of the center of rotation (CoR) or angular and translational relative motion.
These parameters give, however, valuable
information on the current state of degeneration of a spinal segment.
With the FXA software it is now possible for the first time to utilize these parameters as part of the diagnosis. Moreover, it is ideally suited to assess the radiographical outcome of orthopedic treatments within clinical studies or post market surveillance.
One key advantage of our software is the operator independence. Smart algorithms avoid the utilization of manual landmark placement, contour identification or image matching “by hand”, which increases accuracy and repeatability.
Some typical analysis parameters are:
- Range of motion (RoM)
- Location and change of the center of rotation (CoR)
- Translational instabilities
- Implant migration, sintering or loosening
- Implant function (in-vitro or in-vivo)
- Relative motion quantification between implant components or the bone-implant interface
- Fusion assessment by means of analyzing the segmental RoM
- Static measurements, e.g. intervertebral disc height, lystheses, cross sectional areas of the foramina or spinal channel
- Lordosis angle
- Saggital profile
