Spiral CT ScanSpiral CT Scan

Spiral computed tomography is a computed tomography, technology involving movement in a spiral pattern for the purpose of increasing resolution. Most modern hospitals currently use spiral CT scanners. CT beam types have included parallel beams, fan-beams, and cone-beams.
In spiral cone-beam computed tomography, the beam is in the shape of a beam or a cone.

Helical (or spiral) cone beam computed tomography (commonly abbreviated CBCT) is a type of three dimensional computed tomography (CT) in which the source (usually of x-rays) describes a helical trajectory relative to the object while a two dimensional array of detectors measures the transmitted radiation on part of a cone of rays emanating from the source. In practical helical cone beam x-ray CT machines, the source and array of detectors are mounted on a rotating gantry while the patient is moved axially at a uniform rate. Earlier x-ray CT scanners imaged one slice at a time by rotating source and one dimensional array of detectors while the patient remained static. The helical scan method reduces the x-ray dose to the patient required for a given resolution while scanning more quickly.
