spiral computed tomography

Also found in: Dictionary, Encyclopedia, Wikipedia.

spi·ral com·put·ed to·mog·ra·phy

computed tomography in which the x-ray tube continuously revolves around the patient, who is simultaneously moved longitudinally; computer interpolation allows reconstruction of standard transverse scans or images in any preferred plane.
Synonym(s): helical computed tomography, helical CT, spiral CT

spiral computed tomography

Helical scanning Imaging CT imaging based on 'slip-ring' technology, in which a large image volume is acquired by continuous rotation of the detector. See Computed tomography, Cf High-resolution computed tomography.

spiral computed tomography

A development of CT scanning that is rapid, allows scanning of a large body volume on a single breath-hold, and provides high-quality two- and three-dimensional images. The X-ray tube rotates around the patient in a spiral, taking less than a second to complete one rotatation. Up top 60 rotations are possible. A special surface-shading display reveals astonishing detail, especially of bones.
