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 ...
This technology is the fastest generation of CT scanner to date. Third-generation spiral CT designs, especially those with 64 detector rows, 3×360°/sec rotation speeds, and designed for cardiac imaging, are largely replacing the EBT design from a commercial and medical perspective. However, electron beam CT still offers sweep speeds of ...

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 ...
Elscint (perhaps a portmanteau of the words "electronic" and "scientific, but more likely of "El" as in "El Al", and "Scint", as in scintillation, referring to the type of radiation detector used in Nuclear Medicine as in Elscint's first products.) was founded in 1969 by Dr. Avraham Suhami, who was a nuclear physics professor at the Technion – Israel Institute of Technology at the time ...
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.
Compared to a mobile C-arm, which is classically used in surgery, CT scanners and fixed C-arms work on a much higher energy level, which induces higher dose. Therefore, it is very important to monitor radiation dose applied in a hybrid operating room both for the patient and the medical staff.
