ABSTRACT:
An x-ray diagnostics installation includes a device for positioning a radiation emitter such that the reference ray of an emitted ray beam always and automatically intersects a reference axis that is stationary with reference to said device at an acute angle .alpha. when the radiation emitter is coupled to the device. X-ray exposures for tomosynthesis can thus be produced in a simple way.
