Abstract:
A triple race bearing reconfigure lock for a dual detector gamma camera, comprising:a stationary race serving as a support frame; a first movable race having a first detector mounted thereon, said first movable race being coupled to said stationary race and being movable with respect to said stationary race; a second movable race having a second detector mounted thereon, said second movable race being coupled to said first movable race and being movable with respect to said first movable race; a lock assembly mounted on said second movable race; a plurality of lock segments mounted on said first movable race, each of said plurality of lock segments being positioned at a location on said first movable race corresponding to a different configuration angle for configuring the relative orientation between said first and second detectors; a locking pocket formed in said stationary race; said lock assembly having a slide mechanism containing a channel, said slide mechanism being movable outward from said lock assembly to a first extended position spanning said first movable race, wherein said slide mechanism engages with said locking pocket in said first extended position allowing said lock segments to be rotated through said channel; and said slide mechanism being movable inward toward said lock assembly to a second retracted position wherein said channel is retracted such that said slide mechanism engages with one of said lock segments and prevents said engaged lock segment from rotating with respect to said slide mechanism when said one of said lock segments is aligned with said slide mechanism.
