Patent ID: 8246247

Claim:
A rotor for a gantry of a computed tomography apparatus, comprising: a rotor structure configured to mount computed tomography image data acquisition components thereon, said rotor structure being configured to rotate around a rotation center, with rotation of said rotor structure around said rotation center with said components mounted thereon producing localized force stresses in said rotor structure; and said rotor structure comprising a plurality of structural bars joined together in a structural configuration, at least some of said structural bars comprising a composite, reinforcement material formed by carbon fibers selected from the group consisting of short fibers and long fibers, each of said shaped-bodies structural bars forming a structural element of said rotor structure and having a shape, orientation and location in said rotor structure that reinforces said rotor structure against said localized force stresses; and said structural configuration comprising a plurality of right triangles and trapezoids formed by said structural bars, each of said right triangles comprising a base and a hypotenuse and the respective bases of said right triangles defining a base plane and each of said triangles being oriented at 90° relative to said base plane, and the respective hypotenuses of said right triangles defining a hypotenuse plane, and said trapezoids being located in said hypotenuse plane.
