Abstract
A dual C-arm angiographic device for flat panel x-ray receptor (“dual C-arm gantry”) comprises: a base attached to the floor; an outer C-shaped track non-movably attached to the base; a crawler carriage that moves along the outer track; and a counterweighted, inner C-shaped instrument bracket (“inner C-arm”) pivotally attached to the crawler carriage. A detector/counterweight housing, flat-panel x-ray receptor, and x-ray tube and collimator are attached to the inner C-arm. The bottom end of the outer track terminates at the base, such that the outer track arches over the side and top of a separate patient support table. Additionally, the outer track, crawler carriage, and inner C-arm are mutually configured such that the dual C-arm gantry is capable of full spherical angulation and of providing a full range of clinical positioning, while minimizing interference with clinical use patterns (i.e., the head end of the table is left clear for all angulations).
