Abstract
An improved X-ray tomography system having an X-ray source, X-ray detector assembly and support means including a frame supporting a rotatable drum on which at least the source is mounted for rotation in a scanning plane about an axis of rotation. The rotatable drum is supported for centerless rotation on a cradle formed by resilient rollers, with the top half of the drum free to expand or contract as a result of temperature changes. The rollers are resilient so as to dampen vibration transfer between the frame and drum.
Claims9
In an improved X-ray tomography system comprising a rotatable assembly including an X-ray source for generating X-rays, X-ray detection means for detecting X-rays generated by said source, and support means including frame means for supporting said rotatable assembly for rotation so that said at least X-ray source rotates in a scanning plane, said rotatable assembly including an outer periphery, the improvement wherein
- said support means further including a plurality of rollers in contact with at least the outer periphery of said rotatable assembly, at least the circular surfaces of said rollers being formed of resilient material for damping transmission of vibration from said frame to said rotatable assembly.
In an improved X-ray tomography system comprising a rotatable assembly including an X-ray source for generating X-rays, X-ray detection means for detecting X-rays generated by said source, and support means including frame means for supporting said rotatable assembly for rotation about an axis of rotation so that at least said X-ray source rotates in a scanning plane about said rotation axis, the improvement wherein:
- said support means further includes a plurality of rollers compliantly mounted and fixed relative to said frame means and constructed and arranged for contacting said rotatable assembly such that at any time said rollers contact said rotatable assembly only in a region below said rotation axis so as to rotatably support said rotatable assembly for centerless rotation in plane parallel or coplanar to said scanning plane.
