Guidelines for standardization of radiostereometry (RSA) of implants

TL;DR: 6 research centers have agreed upon standards for terminology, description and use of RSA arrangement including radiographic set-up and techniques, which will form the basis of a detailed standardization protocol under supervision of ISO and the European Standards Working Group on Joint Replacement Implants.
Journal ArticleDOI

Experimental assessment of precision and accuracy of radiostereometric analysis for the determination of polyethylene wear in a total hip replacement model

TL;DR: A phantom model based on actual total hip replacement (THR) components was developed and test to simulate the true penetration of the femoral head resulting from polyethylene wear to study both the accuracy and the precision of radiostereometric analysis, RSA, in measuring wear.
Journal ArticleDOI

The precision of radiostereometric measurements. Manual vs. digital measurements.

TL;DR: Increased precision of radiostereometric measurements may be used to increase the statistical power of future randomised studies and to study new fields in orthopaedics requiring higher precision than has been available with RSA based on manual measurements.
Journal ArticleDOI

RSA wear measurements with or without markers in total hip arthroplasty.

TL;DR: Novel algorithms for radiostereometric measurements of the femoral head and metal-backed, hemi-spherical cups of a total hip replacement are presented and evaluated on phantom images and clinical double examinations of 20 patients to help to save patient data in current RSA studies lost due to insufficiently marked cups.
Journal ArticleDOI

Estimation of Tree Stem Attributes Using Terrestrial Photogrammetry with a Camera Rig

TL;DR: A novel photogrammetric method for field plot inventory, designed for simplicity and time efficiency on-site, and easily extended to multiple station image schemas, which could be a useful technique for measuring stem attributes in the forest.
