Abstract:
A radiology instrument comprising an X-ray tube linked with a detector, a plane of the detector being substantially perpendicular to a line of sight passing approximately through a focus of the tube and through a middle of plane of the detector, the tube and the detector being capable of occupying positions in rotation around a body by means of a support device, the support device comprising a pedestal of overall L-shape resting on a floor, with a substantially horizontal base, a substantially vertical post and an axis of rotation passing through one end of the base, the post being fixed to the other end of the base and being parallel to said axis of rotation, an articulation about a substantially vertical fourth axis arranged in said post allowing an upper part of the instrument to rotate about said fourth axis relative to a lower part of the instrument, a bracket which is fixed to the top of the articulated post and can rotate about a horizontal axis, and a C-shaped arm mounted on the bracket and capable of rotating about an axis substantially perpendicular to said horizontal axis by sliding on the bracket, the tube and the detector being mounted on said C-shaped arm and facing one another, the axis of the bracket and the axis of the arm being secant at a point in space referred to as the isocenter and means for moving the isocenter continuously along a longitudinal axis of the body.
