Examples of tomography in the following topics:

  • Emission Topography

    • Positron emission tomography is a nuclear medical imaging technique that produces a three-dimensional image of processes in the body.
    • Positron emission tomography (PET) is a nuclear medical imaging technique that produces a three-dimensional image or picture of functional processes in the body.
    • A technique much like the reconstruction of computed tomography (CT) and single-photon emission computed tomography (SPECT) data is more commonly used, although the data set collected in PET is much poorer than CT, so reconstruction techniques are more difficult.
    • Discuss possibility of uses of positron emission tomography with other diagnostic techniques.
  • X-Ray Imaging and CT Scans

    • Tomography refers to imaging by sections, or sectioning. demonstrates this concept.
    • CT scans, or computed tomography scans use a combination of X-ray radiography and tomography to produce slices of areas of the human body.
  • NMR and MRIs

    • Magnetic resonance imaging (MRI), also called nuclear magnetic resonance imaging (NMRI) or magnetic resonance tomography (MRT), is a medical imaging technique used in radiology to visualize internal structures of the body in detail.
    • MRI shows a marked contrast between the different soft tissues of the body, making it especially useful in imaging the brain, the muscles, the heart, and cancerous tissue—as compared with other medical imaging techniques such as computed tomography (CT) or X-rays.
  • Matter and Antimatter

    • Matter-antimatter reactions have practical applications in medical imaging, such as in positron emission tomography (PET).
  • Radiation Detection

    • Scintillators can also be used in neutron and high-energy particle physics experiments, new energy resource exploration, x-ray security, nuclear cameras, computed tomography, and gas exploration.
