Crowther criterion
The conventional method to evaluate the resolution of an tomography reconstruction is determined by the Crowther criterion.

CT scan
A CT scan, also known as computed tomography scan, makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object, allowing the user to see inside the object without cutting.

Electron cryotomography
Electron cryotomography (CryoET) is an imaging technique used to produce high-resolution (~4 nm) three-dimensional views of samples, typically biological macromolecules and cells.

High-resolution transmission electron microscopy
High-resolution transmission electron microscopy (HRTEM) (or HREM) is an imaging mode of the transmission electron microscope (TEM) that allows for direct imaging of the atomic structure of the sample.

IMOD (software)
IMOD is an open-source, cross-platform suite of modeling, display and image processing programs used for 3D reconstruction and modeling of microscopy images with a special emphasis on electron microscopy data.

Macromolecule
A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers).

Nanometre
The nanometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the metric system, equal to one billionth (short scale) of a metre (m).

Peptide
Peptides (from Gr.: πεπτός, peptós "digested"; derived from πέσσειν, péssein "to digest") are short chains of amino acid monomers linked by peptide (amide) bonds.

Three-dimensional space
Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point).

Tomographic reconstruction
Tomographic reconstruction is a type of multidimensional inverse problem where the challenge is to yield an estimate of a specific system from a finite number of projections.
