Adora RSA

Adora RSA is a pioneer. Developed to meet the needs of RSA researchers, this system has become instrumental in further expanding our knowledge of joint anatomy and orthopeadic implant quality, ultimately leading to increased patient safety.


RSA, or Röntgen Stereometric Analysis, is a method of analysis, which is used to predict the long-term performance of orthopaedic implants. Long term studies have documented, that the micro-migration during the first two years after e.g. TKA or THA has predictive value regarding the longevity of the implant. RSA is thus used as post-op reference and for regular controls and image acquisition has traditionally been a time-consuming and predominantly manual process in the Radiological Department.


Adora RSA was designed to make the RSA image acquisition process faster, more automated, easier to perform and the results more accurate. Twin tubes are automatically positioned at pre-set angles and exposure takes place simultaneously, preventing micro-movements and delayed human reactions from affecting the results of the analysis. The Canon DR detectors and the powerful image processing software ensure that your RSA images are crisp and clear, making the tantalum markers much easier to identify – even at low dose exposure.


Adora RSA is a versatile solution that fits your needs. It is capable of switching between RSA and regular examinations at the touch of a button, making it possible to capture ordinary and RSA images in a single study and effectively integrate the Adora RSA in the Radiological Department. Whether you are performing RSA studies in a room for 10% or 90% of the time, Adora RSA is capable of meeting your demands, retaining full capacity for DR procedures. Dynamic imaging, used in both dynamic RSA studies as well as in a range of fluoroscopic examinations, is also available with the RSAd version.


The Adora RSA represents pioneering design for optimal precision and reliability. NRT continues the efforts to further develop the technology in the AutoRSA project, an ongoing collaboration between Aarhus University, Aarhus University Hospital and Aalborg University Hospital aiming at an integrated diagnostic platform for QA of artificial joint implants and dynamic studies of moving joints. The project is co-financed by the Innovation Fund Denmark
