Annotation
do not confuse with SPIRAL CONE-BEAM COMPUTED TOMOGRAPHY
Scope Note
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
