Abstract
A CT scanner comprises a rotatable gantry 1 carrying an X-ray source 3 which provides a fan-shaped beam of X-rays and an X-ray detector 10 which scans the X-ray intensity along a line in the plain of the beam. The gantry is rotatable about an axis A relative to a couch 2 which supports the patient under investigation. The X-ray detector 10 comprises two concentric X-ray masks exposed around a scintillator tube; the two masks having helical X-ray transmissive apertures, the helices being of opposed orientation so that rotation of the masks in opposite directions causes the exposed area of the scintillator tube to move along its length.
