  2. Gamma camera - Wikipedia

    en.wikipedia.org/wiki/Gamma_camera

    A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...

    Film stock made of nitrate, acetate, or polyester bases is the traditional medium for capturing the numerous frames of a motion picture, widely used until the emergence of digital film in the late 20th century. film theory film transition film treatment filmmaking. Sometimes used interchangeably with film production.

  4. Industrial radiography - Wikipedia

    en.wikipedia.org/wiki/Industrial_radiography

    Making a radiograph. Industrial radiography is a modality of non-destructive testing that uses ionizing radiation to inspect materials and components with the objective of locating and quantifying defects and degradation in material properties that would lead to the failure of engineering structures.

  5. Scintigraphy - Wikipedia

    en.wikipedia.org/wiki/Scintigraphy

    Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...

  6. Tomography - Wikipedia

    en.wikipedia.org/wiki/Tomography

    Volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired, for example, by a CT , MRI , or MicroCT scanner .

  7. Radiography - Wikipedia

    en.wikipedia.org/wiki/Radiography

    Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.

  8. Medical imaging - Wikipedia

    en.wikipedia.org/wiki/Medical_imaging

    Then, gamma cameras capture and form two-dimensional [12] images from the radiation emitted by the radiopharmaceuticals. SPECT is a 3D tomographic technique that uses gamma camera data from many projections and can be reconstructed in different planes. A dual detector head gamma camera combined with a CT scanner, which provides localization of ...

  9. Single-photon emission computed tomography - Wikipedia

    en.wikipedia.org/wiki/Single-photon_emission...

    Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [ 2 ] but is able to provide true 3D information.
