Wikipedia

  1. Tomography

    Tomography is imaging by sections or sectioning that uses any kind of penetrating wave. The method is used in radiology, archaeology, biology, atmospheric science, geophysics, oceanography, plasma physics, materials science, astrophysics, quantum information, and other areas of science. The word tomography is derived from Ancient Greek τόμος tomos, "slice, section" and γράφω graphō, "to write" or, in this context as well, "to describe." A device used in tomography is called a tomograph, while the image produced is a tomogram. In many cases, the production of these images is based on the mathematical procedure tomographic reconstruction, such as X-ray computed tomography technically being produced from multiple projectional radiographs. Many different reconstruction algorithms exist. Most algorithms fall into one of two categories: filtered back projection (FBP) and iterative reconstruction (IR). These procedures give inexact results: they represent a compromise between accuracy and computation time required. FBP demands fewer computational resources, while IR generally produces fewer artifacts (errors in the reconstruction) at a higher computing cost.Although MRI, Optical coherence tomography and ultrasound are transmission methods, they typically do not require movement of the transmitter to acquire data from different directions. In MRI, both projections and higher spatial harmonics are sampled by applying spatially-varying magnetic fields; no moving parts are necessary to generate an image. On the other hand, since ultrasound and optical coherence tomography uses time-of-flight to spatially encode the received signal, it is not strictly a tomographic method and does not require multiple image acquisitions.

  1. tomography

    Tomography is a medical imaging technique that captures detailed, cross-sectional images of the internal structures of the body. These images are often 3D and are produced using various methods like X-rays, ultrasound, or magnetic resonance, allowing doctors to accurately diagnose and treat different medical conditions. This technique can be applied to various body parts including the brain, heart, bones, and blood vessels among others.

  1. Tomography

    Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in tomography is called a tomograph, while the image produced is a tomogram. Tomography as the computed tomographic scanner was invented by Sir Godfrey Hounsfield, and thereby made an exceptional contribution to medicine. The method is used in radiology, archaeology, biology, geophysics, oceanography, materials science, astrophysics, quantum Information, and other sciences. In most cases it is based on the mathematical procedure called tomographic reconstruction.

Examples of tomography in a Sentence

  1. Henry Paulson:

    And oftentimes, we also will do brain metabolism imaging, it’s Positron Emission Tomography or PET imaging, and that can tell us which parts of the frontal lobes or the temporal lobes are involved.

  2. Sanjay Gupta:

    I don't want to suggest that everyone who hits their head needs to go get a [ computed tomography also known as a CT or CAT) ] scan, most do not need that obviously. But if it's a significant blow, you're on blood thinners... and again those symptoms : worsening headaches, confusion, nausea, vomiting, slurring of speech, things like that are unusual. You should definitely go get that checked out.
