electron microscopy tomography abbr., 3D TEM; ET otherwise electron tomography; scanning transmission electron tomography (rus. томография, электронная) — three-dimensional imaging of cells and subcellular structures using transmission electronic microscopy.


Electron tomography is a relatively new and leading approach that is used to study intracellular organelles and supramolecular assemblies in cells by means of electron microscopy. Like other tomographic techniques (see X-ray computed tomography), electron tomography reconstructs the three-dimensional structure of an object. The resolution can be as high as 2 nm, and biological samples to be analysed can be up to 1 micron thick.
