  • measurements
  • Tomography involves taking measurements around the periphery of an object (e.g. process vessel or patient) to determine what is going on inside. (wikipedia.org)
  • Quantum tomography or quantum state tomography is the process of reconstructing the quantum state (density matrix) for a source of quantum systems by measurements on the systems coming from the source. (wikipedia.org)
  • The general principle behind quantum state tomography is that by repeatedly performing many different measurements on quantum systems described by identical density matrices, frequency counts can be used to infer probabilities, and these probabilities are combined with Born's rule to determine a density matrix which fits the best with the observations. (wikipedia.org)
  • Unlike a measurement on a single system, which determines the system's current state after the measurement (in general, the act of making a measurement alters the quantum state), quantum tomography works to determine the state(s) prior to the measurements. (wikipedia.org)
  • Ocean acoustic tomography integrates temperature variations over large distances, that is, the measured travel times result from the accumulated effects of all the temperature variations along the acoustic path, hence measurements by the technique are inherently averaging. (wikipedia.org)
  • Image
  • A laser detector measures the intensity drop and the data is collected as the laser detector moves across the breast creating a tomography image. (wikipedia.org)

  • A device used in tomography is called a tomograph, while the image produced is a tomogram. (wikipedia.org)
  • Seismic tomography is similar to medical x-ray computed tomography (CT scan) in that a computer processes receiver data to produce a 3D image, although CT scans use attenuation instead of traveltime difference. (wikipedia.org)
  • Since muons are much more deeply penetrating than X-rays, muon tomography can be used to image through much thicker material than x-ray based tomography such as CT scanning. (wikipedia.org)

  • citation needed
  • citation needed] In fluorescence tomography, the fluorescence signal transmitted through the tissue is normalized by the excitation signal transmitted through the tissue, and so many of the fluorescence tomography systems do not require the use of time-resolved or frequency domain data, although research is still ongoing in this area.
