ABSTRACT:
In an illustrated embodiment, the cables between the x-ray generator and the angularly movable x-ray source and between the angularly movable radiation detector and the processing circuitry are guided by means of an epicyclically movable planetary member operating between relatively rotatable inner and outer wheel members. The x-ray source and detector may be secured with the inner member which then may rotate through an angle of about 360.degree. during a measurement operation. The cables may initially extend about substantially the entire perimeter of the inner member and then loop about the planetary member and be attached at a convenient point to the stationary outer member. The cables at one end could then extend from the inner member to the x-ray source and detector, and at the opposite end from the stationary outer member to the x-ray generator and other stationary circuit components. In this example, during rotation of the inner member with the x-ray source and detector, the cables are progressively unwound from the periphery of the inner member and transferred by the planetary member to the inner perimeter of the stationary outer member. In this way, the cables may be reliably guided during a 360.degree. rotation of the measurement apparatus, for example. One or more further planetary members may be interposed between the inner and outer members in guiding relation to the cables.
