Roentgen stereophotogrammetry (RSA) is a precise imaging technique used primarily in the field of medical imaging and biomechanics, particularly for analyzing the motion and position of implants and bones in three-dimensional space. It involves the use of X-ray images to capture the position of markers placed on or within the body, typically around surgical implants, such as joint replacements.
