Abstract

A object handling system is moveable between various diagnostic imaging apparatus for imaging thereby. The handling system has an object handling computer 34 for storing object identification data and imaging data. Selectively linking the object handling computer 34 with a first imaging system provides the first imaging system with access to the object identification data and imaging data for use in the production of diagnostic images thereby. Similarly, the object identification data and imaging data are available to a second imaging system for use in the production of diagnostic images thereby when the object handling computer 34 is selectively linked thereto. The object identification data is associated with the diagnostic images produced by various imaging system for subsequent correlation of the object with the diagnostic images of the object. The object handling computer 34 also modifies various automated table movement apparatus as a function of the imaging system to which the handling system is selectively linked.
