ABSTRACT:
A radiographic imaging system coupled to a movable table for repositioning subject matter at the conclusion of a scanning of an area of the subject matter. The imaging system is further coupled to a plural axis recording system in which a recording implement, such as a flashing light source, is driven in synchronism with a scanning motion of the imaging system along a recording medium such as a photographic film. Controller circuitry is coupled between the movable table, the imaging system and the recording system for synchronizing their respective operations and for selectably scaling the movement of a drive unit relative to the movement of the scanning. A large subject such as a complete human being may be scanned by repositioning the subject and the movable table at the conclusion of each of a sequence of area scans of the imaging system, and by scaling the output of the scanning system so that the successively scanned regions of the subject can be recorded upon a single standard size x-ray film plate.
