A 3D calibration body for spatial calibration of an optical imaging system includes a transparent body and calibration marks embedded in a volume of the transparent body. At least some of the calibration marks are selectively activatable and deactivatable, wherein an activated calibration mark is visible in the visible spectral range and a deactivated calibration mark is not visible in the visible spectral range.
