Cryo-electron tomography — (cryo ET or electron cryotomography) is a type of electron cryomicroscopy where tomography is used to obtain a 3D reconstruction of a sample from tilted 2D images at cryogenic temperatures. A cryoelectron tomography can be used to obtain… … Wikipedia
Tomography — Basic principle of tomography: superposition free tomographic cross sections S1 and S2 compared with the projected image P Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in… … Wikipedia

Electron beam tomography — (EBT) is a specific form of computed axial tomography (CAT or CT) in which the X ray tube is not mechanically spun in order to rotate the source of X ray photons. This different design was explicitly developed to better image heart structures… … Wikipedia
tomography — Making of a radiographic image of a selected plane by means of reciprocal linear or curved motion of the x ray tube and film cassette; images of all other planes are blurred (“out of focus”) by being relatively displaced on the film. SYN:… … Medical dictionary
electron beam computed tomography — (EBCT) ultrafast computed tomography done with a scanner in which the patient is surrounded by a large circular anode that emits x rays as the electron beam is guided around it … Medical dictionary
Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… … Wikipedia
Cryo-electron microscopy — CryoEM image of GroEL suspended in vitreous ice at 50,000X magnification. Cryo electron microscopy (cryo EM), or electron cryomicroscopy, is a form of transmission electron microscopy (EM) where the sample is studied at cryogenic temperatures… … Wikipedia
Electron beam computerized tomography (EBCT) — A new (and controversial) noninvasive test for the detection of coronary artery disease (CAD). EBCT, or Ultrafast CT (as the technique will be termed here) is designed to measure calcium deposits in the coronary arteries. In patients with CAD,… … Medical dictionary
Computed tomography — tomos (slice) and graphein (to write).Computed tomography was originally known as the EMI scan as it was developed at a research branch of EMI, a company best known today for its music and recording business. It was later known as computed axial… … Wikipedia
