【 摘 要 】

Roentgen stereophotogrammetric analysis(RSA) was first introduced by Selvik in 1974 toassess implant micromotion.1 The standardRSA setup involves two synchronous X-raytubes directed at a 20° angle relative to thenormal vector, and a calibration plate positioned underneath the table. The calibrationbox contains reference markers to define thecoordinates and standardize the position ofthe foci.
