  2. Radon transform - Wikipedia

    en.wikipedia.org/wiki/Radon_transform

    Radon transform. Maps f on the (x, y)-domain to Rf on the (α, s)-domain.. In mathematics, the Radon transform is the integral transform which takes a function f defined on the plane to a function Rf defined on the (two-dimensional) space of lines in the plane, whose value at a particular line is equal to the line integral of the function over that line.

  3. Tomographic reconstruction - Wikipedia

    en.wikipedia.org/wiki/Tomographic_reconstruction

    A notable example of applications is the reconstruction of computed tomography (CT) where cross-sectional images of patients are obtained in non-invasive manner. Recent developments have seen the Radon transform and its inverse used for tasks related to realistic object insertion required for testing and evaluating computed tomography use in ...

  4. Projection-slice theorem - Wikipedia

    en.wikipedia.org/wiki/Projection-slice_theorem

    Take a two-dimensional function f(r), project (e.g. using the Radon transform) it onto a (one-dimensional) line, and do a Fourier transform of that projection. Take that same function, but do a two-dimensional Fourier transform first, and then slice it through its origin, which is parallel to the projection line. In operator terms, if

  5. History of computed tomography - Wikipedia

    en.wikipedia.org/wiki/History_of_computed_tomography

    Hounsfield's prototype CT scanner A historic EMI-Scanner Mark I, alongside the minicomputer used to process the CT image data. The history of X-ray computed tomography (CT) dates back to at least 1917 with the mathematical theory of the Radon transform.

    In conventional CT machines, an X-ray tube and detector are physically rotated behind a circular shroud (see the image above right). An alternative, short lived design, known as electron beam tomography (EBT), used electromagnetic deflection of an electron beam within a very large conical X-ray tube and a stationary array of detectors to achieve very high temporal resolution, for imaging of ...

  7. Optical projection tomography - Wikipedia

    en.wikipedia.org/wiki/Optical_projection_tomography

    However, essential mathematics and reconstruction algorithms used for CT and OPT are similar; for example, radon transform or iterative reconstruction based on projection data are used in both medical CT scan and OPT for 3D reconstruction. Both medical CT and OPT compute 3D volumes based on transmission of the photon through the material of ...

    After being the subject of cultural debates throughout her rookie season, Caitlin Clark admitted to feeling "privilege" as a White woman.

  9. Ultrasound computer tomography - Wikipedia

    en.wikipedia.org/wiki/Ultrasound_computer_tomography

    Tomographic reconstruction methods used in USCT systems for transmission information based imaging are classical inverse radon transform and fourier slice theorem and derived algorithms (cone beam etc.). As advanced alternatives, ART-based approaches are also utilized.
