Helical cone beam computed tomography
Helical (or spiral) cone beam computed tomography 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 eminating from the source. Willi Kalender, who is credited with the invention prefers the term Spiral scan CT, arguing that spiral is synonymous with helical: for example as used in 'spiral staircase'.
