  2. CT scan - Wikipedia

    en.wikipedia.org/wiki/CT_scan

    Drawing of CT fan beam and patient in a CT imaging system CT scan of the thorax. The axial slice (right) is the image that corresponds to number 2/33 on the coronal slice (left). Spinning tube, commonly called spiral CT, or helical CT, is an imaging technique in which an entire X-ray tube is spun around the central axis of the area being ...

    en.wikipedia.org/wiki/History_of_computed_tomography

    The history of X-ray computed tomography (CT) dates back to at least 1917 with the mathematical theory of the Radon transform. [1][2] In the early 1900s an Italian radiologist named Alessandro Vallebona invented tomography (named "stratigrafia") which used radiographic film to see a single slice of the body. [3][4][5][6][7][8][9][10][11] It was ...

    64-slice CT scanner originally developed by Elscint, now a Philips product [2]. Elscint was an Israeli technology company that developed, manufactured and sold medical imaging solutions, including: Nuclear medicine, computed tomography magnetic resonance imaging and X-ray scanners.

  5. Operation of computed tomography - Wikipedia

    en.wikipedia.org/wiki/Operation_of_computed...

    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 ...

    Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...

    MeSH. D014057. OPS-301 code. 3-26. [edit on Wikidata] Electron beam computed tomography (EBCT) is a specific form of computed tomography (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 that never stop moving ...

  8. Cone beam computed tomography - Wikipedia

    en.wikipedia.org/wiki/Cone_beam_computed_tomography

    Cone Beam CT scanner. MeSH. D054894. Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone. [1]

  9. Full-body CT scan - Wikipedia

    en.wikipedia.org/wiki/Full-body_CT_scan

    Full-body CT scan. A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography (CAT) scan technology is used, it is known as a full-body CT scan, though many medical imaging technologies can perform full-body scans.
