Tilting a specimen may change the magnification and the image rotation for electron-microscopic images, because re-focusing with an objective lens is required to correct for the height variation of the tilted specimen. Computer simulation is performed to analyse the effect of variations in the magnification and the image rotation on the three-dimensional reconstruction in electron tomography.
Keywords magnification, image rotation, specimen tilt, three-dimensional reconstruction, electron microscopy
