PY - 2011 T2 - Venous and Lymphatic Diseases AB - The basic single-detector computed tomography (CT) scanner operates with a single row of detectors mounted opposite an x-ray source on a rotating gantry through which a patient moves during image acquisition. In 1992, the first dual-section helical CT scanner was introduced, which had two rows of detectors.1 In subsequent years, technology has continued to improve, with additional rows of detectors added to the rotating gantry. Currently, multidetector scanners with a single x-ray source are available with up to 128 rows of detectors. Scanners with two x-ray sources have 256 or more detectors.
