Radio Stereometric Analysis

0.5mm Tantalum Marker Beads

X-medics offers 0.5mm tantalum RSA marker beads suitable for permanent implantation inside the human body during clinical trials.  The products are not CE-marked nor FDA-registered, and are delivered non-sterile. However, X-medics is participating in a number of clinical studies, and we plan to offer a CE-marked product at a later stage. In addition, we can support you with documentation relevant for your technical file, in case your organisation is preparing to place a CE-marked product on the market.

Unique Biocompatibility

Spherical tantalum markers have been used for more than 30 years for roentgen (x-ray) stereophotogrammetric or radio stereometric analysis without any severe events reported. X-medics’ tantalum RSA markers have today been used in clinical trials on several thousand patients. X-medics markers are made from surgical grade tantalum. Tantalum is biocompatible, well tolerated by the body, and readily observed as a distinct point in the radiograph. As tantalum markers are radio-opaque and requires only a low x-ray dose for examination.
