This mummy is unusual in that it has been CT scanned three times with different generations of imaging technology: first in 1991 using a GE single-slice helical scanner, next in July 2008 with a 64-slice Philips Brilliance 64 scanner, and most recently in late September 2008 using a Philips iCT 256-slice CT scanner.
During 1999 and 2000, Elscint and Elbit Medical Imaging sold their imaging activities to GE Healthcare and to Philips Medical Systems for approximately $600 million. [8] In 1992, Elscint introduced Elscint CT Twin, the world's first multi-slice (actually it was double-slice) CT scanner. This system could acquire two images with every rotation ...
A notable example of applications is the reconstruction of computed tomography (CT) where cross-sectional images of patients are obtained in non-invasive manner. Recent developments have seen the Radon transform and its inverse used for tasks related to realistic object insertion required for testing and evaluating computed tomography use in ...
In 1974, work on CT was started and the first CT machine was installed in 1976. In June 1980, the company acquired the CT scanner business of EMI. [8] GE Signa series MRI Scanner, used at Narayana Multispeciality Hospital, Jaipur. In 1982, the company set up a joint venture with Yokogawa Electric. It changed its name to GE Healthcare Japan ...
Drawing of CT fan beam and patient in a CT imaging system CT scan of the thorax. The axial slice (right) is the image that corresponds to number 2/33 on the coronal slice (left). Spinning tube, commonly called spiral CT, or helical CT, is an imaging technique in which an entire X-ray tube is spun around the central axis of the area being ...
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 ...
The portable CT scanner does not replace the fixed CT suite. An example of this type of machine is the Siemens Healthineers SOMATOM On.site. In 2008 Siemens introduced a new generation of scanner that was able to take an image in less than 1 second, fast enough to produce clear images of beating hearts and coronary arteries.
These scanners could scan the body in 2–5 seconds, thereby eliminating motion artifacts due to breathing. The HPS 1440 scanner was introduced in 1985 as an ultra high resolution CT scanner. These scanners were of the fourth generation design, in which there was a stationary ring of detectors and the x-ray tube rotating inside the detector ring.
