C.29.1.3.1.1 Surface Model Scaling Factor

Surface Model Scaling Factor (0068,6390) is used to scale dimensions of the surface mesh representation to match the real dimensions of the implant measured in millimeters.

This Attribute does not compensate for any radiographic geometric magnification effect caused by the diverging X-ray beam in the projection patient images used for planning. Such compensation is the responsibility of the application based on calibration of the imaging process.
