MeSH Heading: Tomography, Spiral Computed
Tree Number(s): E01.370.350.350.810.800; E01.370.350.600.350.700.810.800; E01.370.350.700.700.810.800; E01.370.350.700.810.810.800; E01.370.350.825.810.810.800
Unique ID: D036542
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D036542
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.
