2. Industrial computed tomography - Wikipedia

   en.wikipedia.org/wiki/Industrial_computed_tomography

   Industrial computed tomography (CT) scanning is any computer-aided tomographic process, usually X-ray computed tomography, that uses irradiation to produce three-dimensional internal and external representations of a scanned object. Industrial CT scanning has been used in many areas of industry for internal inspection of components.

3. Lung cancer screening - Wikipedia

   en.wikipedia.org/wiki/Lung_cancer_screening

   The currently used low dose CT scan results in a radiation exposure of about 2 millisieverts (equal to roughly 20 two-view chest x-rays). [11] It has been estimated that radiation exposure from repeated screening studies could induce cancer formation in a small percentage of screened subjects, so this risk should be mitigated by a (relatively ...

4. 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 ...

5. Cone-beam spiral computed tomography - Wikipedia

   en.wikipedia.org/wiki/Cone-beam_spiral_computed...

   Cone-beam spiral computed tomography (CT) is a medical imaging technology that has impacted healthcare since its development in the early 1990s. [1] [2] This technology offers advancements over traditional fan-beam CT, including faster scanning speed, higher image quality, and the ability to generate true three-dimensional volumes, even with contrast-enhancement.

   In 2019, the business announced the acquisition of vascular robotics start-up, Corindus, for $1.1 billion (€980 million). [ 56 ] In August 2020, the business announced it would acquire Varian Medical Systems , for $16.4 billion (€13.9 billion), representing a return to radiation therapy after the discontinuation of Siemens' own linear ...

7. CT scan - Wikipedia

   en.wikipedia.org/wiki/CT_scan

   A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.

9. 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 ...
