Additional controversy arose after a 2008 New York Times reported that the 2006, pro-CT scan study in the New England Journal of Medicine had been funded indirectly by the parent company of the Liggett Group, a tobacco company. [25] In 2011, the National Lung Screening Trial found that CT screening offers benefits over other screenings. [26]
Drishti (from Sanskrit दृष्टि dr̥ṣţi, meaning "vision" or "insight") is a multi-platform, open-source volume-exploration and presentation tool. [1] Written for visualizing tomography data, electron-microscopy data and the like, it aims to ease understanding of data sets and to assist with conveying that understanding to the research community or to lay persons.
Contrast agents are sometimes used in CT scans of the chest to accentuate or enhance the differences in radiopacity between vascularized and less vascularized structures, but a standard chest CT scan is usually non-contrasted (i.e. "plain") and relies on different algorithms to produce various series of digitalized images known as view or "window".
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 ...
Most radiation therapy is planned using the results of a 3D CT scan. A 3D scan largely presents a snapshot of the body at a particular point in time, however due to the time of the acquisition, in which the patient is likely to have moved in some way (even if only breathing), there will be an element of blurring or averaging in the 3D scan.

With President-elect Donald Trump's recent announcement of former surgeon-turned-TV host Dr. Mehmet Oz to lead the Centers for Medicare and Medicaid Services (CMS), questions are swirling about ...
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.
Patrick's six catches were tied for the game-high. Losers Defense. The Packers and Lions combined for 38 points in Week 9. There were 41 points scored in the second half alone Thursday.
