Abstract
A deformable, inner ring (22) is mounted by spokes (24) to internal structure (26) of a CT scanner. A plurality of circuit boards (32) are bent in a circular arc that is concentric with an inner circular surface of the first ring and secured to the first ring such that the arcuate bend is maintained. Bending the flexible circuit boards into an arc stresses them such that they are cantilevered outward from the first ring, yet are held along the circular arc. A second ring (44) is connected to the outer ends of the circuit boards to assure that both ends of the circuit board are held in like diameter parallel circles. Brackets (52) hold the side edges of the circuit boards straight and linear. In this manner, the circuit boards on which radiation detectors (36) are mounted become a rigid, circular mounting assembly for the radiation detectors and provide the sole support for the second ring.
