Spiral CT

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
