Abstract:
An X-ray diagnostic apparatus for producing panorama slice exposures of body parts of a subject, comprising:a mechanically rotatable unit carrying a source of penetrating radiation and, opposite thereto, a detector camera containing a penetrating radiation-sensitive CCD detector, said rotating unit being adapted for rotating said source of penetrating radiation and said detector camera around a subject to conduct an exposure;said CCD detector comprising a plurality of narrow TDI zones and a plurality of clock-out columns respectively allocated to the TDI zones in said plurality of TDI zones, each TDI zone generating image signals;said detector camera including means for individually reading out the respective image signals from the TDI zones;an image processing unit containing a computer supplied with said image signals from the respective, individual TDI zones;a manually operable input unit which supplies signals to said computer modifying a local offset of individual images obtained from the respective TDI zones;said computer comprising means, after completion of said exposure, for subsequently determining at least one of a sharp slice and a depth of field with the slice position determined by the signals from the input unit and by performing calculations on said image signals from the respective TDI zones; anddisplay means, connected to said image processing unit, for displaying an image of the slice position.
