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.
Their specialization in on-board generators for EMS vehicles made them the perfect fit to create an emergency vehicle that could handle the needs of a mobile CT scanner. NeuroLogica Corporation, a subsidiary of Samsung Electronics, provides the mCT, CereTom, enabling the ambulance to do critical CT scans to determine the status of the stroke.
Recent research has evaluated the use of computer vision based algorithms that operate on the volumetric data used collected as CT-slice images by these and other manufacturers computed tomography (CT) baggage scanner machines for the automatic detection of other threat types (e.g. guns, knives, liquid containers) using 3D object classification.
Electron beam CT scanners are considered a fifth generation CT scanner, with first generation being the pencil beam with translation and rotation, second generation being a fan beam with similar motion to its predecessor, third generation having both rotating fan beam and detectors and fourth generation being a fan beam with a rotating movement but fixed detector.
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 ...
