Contrast is produced by differential interference.
The final frame above is a record of the cell a moment before chemical fixation. The cell was then prepared for electron microscopy by dehydration and embeddment in plastic. Transmission electron microscopy is useful to view high resolution structural determinations. Images are formed by passing a beam of electrons through the specimen. Tomography Electron tomography is an image processing technique used for reconstructing a 3D volume from a set of 2D images collected on the electron microscope.
