Patent ·
OSTI ID:5751119
This patent describes a computed tomography system including an x-ray source producing an x-ray beam along a fan beam axis, an x-ray collimator for controlling the angle of the fan beam axis of a collimated fan beam. It comprises an elongate x-ray absorbing mandrel positioned within the x-ray beam and having a diametrically directed passage extending along the length of the mandrel within the x-ray beam to create one entrance and one exit aperture in the circumference of the mandrel; and a bearing means for holding the mandrel so that it may be rotated about its axis to adjust the angle of the fan beam axis.
