This article applies in general to tomographic reconstruction for all kinds of tomography, but some of the terms and physical descriptions refer directly to X ray computed tomography.

It may also identify widening of the mediastinum suggestive of thymoma, but computed tomography or magnetic resonance imaging (MRI) are more sensitive ways to identify thymomas and are generally done for this reason.

Computed Style

Allan MacLeod Cormack (February 23, 1924 May 7, 1998) was a South African American physicist who won the 1979 Nobel Prize in Physiology or Medicine (along with Godfrey Hounsfield) for his work on X ray computed tomography (CT).

This is to keep all the computed values positive.

Twenty one countries computed average prices for the first quarter.

For more complex features, a 3D model may be obtained using tomography.

The Healthy Life Years indicator (HLY) is a European structural indicator computed by Eurostat.

Network tomography is the study of a network's internal characteristics using information derived from end point data.

Depreciation is computed using the straight line method over the estimated useful life of the asset.

In network tomography, the emphasis is to achieve as accurate a picture of the network with minimal overhead.

In more severe cases a computerized tomography scan (CAT scan) or Magnetic resonance imaging scan (MRI) will be taken.

Another study computed gains of some 200 billion annually if a temporary work visa scheme is designed and adopted multilaterally.

Taking pictures of the brain with computer tomography (CT) or magnetic resonance imaging (MRI) are most useful for diagnosis disease in the brain.

The allowances were computed on the basis of the maximum annual remuneration of 160,000, the comparator remuneration figure since 1 January 2000.

Here you can see the target preview image histogram drawing of the selected image channel. This one is re computed at any settings changes.

And until the work of Kee, Nicita and Olarreaga, ad valorem equivalent estimates had never been computed in such a systematic and extensive way.

Reid's base line is used for an unambiguous definition of the orientation of the human skull in conventional radiography, computer tomography (CT), and magnetic resonance imaging (MRI) studies.

Since electric force, in turn, is the product of the electric charge and the known electric field, the electric charge of the oil drop could be accurately computed.

Recent developments There have been many published papers and tools in the area of network tomography, which aim to monitor the health of various links in a network in real time.

These minor changes in blockages caused a 300 percent improvement in blood flow, and using cardiac positron emission tomography, or PET, scans, blue and black is no blood flow, orange and white is maximal.

Assuming a velocity field formula_20 for formula_21, the eddy currents can be computed from Ohm's law for a moving electrically conducting fluidsubject to the boundary conditions formula_23 at formula_24 and formula_25 as formula_26.

With the increased use of cone beam computerized tomography (CBCT), these shapes are likely to be increasingly more often seen and recognized not only by endodontists but also in the clinical environment of general practice.

This increases the comparability of the results (all effects are computed with reference to the same central point in space) and minimizes the chances of computer programme crashes, more likely when several input factors are changed simultaneously.

In this octant, for each column x between formula_3 and formula_4, there is exactly one row y (computed by the algorithm) containing a pixel of the line, while each row between formula_5 and formula_6 may contain multiple rasterized pixels.

The third decade of penumbral research found a transitional leap as using Positron Emission Tomography (PET) scanning can identify brain tissue with decreased blood flow and Magnetic Resonance Imaging (MRI) has the ability to detect portions of the ischemic tissue that has not yet died.

An orbiter would use radar tomography (that is, the imaging of the interior of a solid body using ground penetrating radar) to probe the target object interior, to study its structure (for example, homogeneous, porous, fractured or simply a loose aggregate of separate boulders) and to assess the seriousness of the threat
