Dental cone beam computed tomography (ct) is a special type of x-ray machine used in situations where regular dental or facial x-rays are not sufficient it is not used routinely because the radiation exposure from this scanner is significantly more than regular dental x-rays. 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 emanating from the source.
