Patent ID: 6935780

Claim:
In an operation-diagnosis apparatus having an exposure unit comprising a radiation receiver and a radiation transmitter and a supporting mechanism for a subject comprising a support plate, having a radiation-transparent region, adapted to receive a subject thereon and a base on which said support plate is adjustably mounted, the improvement comprising: said support plate being mounted to said base for adjustment relative to three spatial axes; a lifting drive in said base for height-adjustment of said support plate; a displacement drive in said base for selective coupling to said support plate for displacing said support plate in at least one of a longitudinal direction of said support plate and a transverse direction of said support plate substantially perpendicular to said longitudinal direction, when coupled to said support plate, and allowing floating displacement of said support plate when uncoupled from said support plate; said support plate being mounted to said base for pivoting around a canting axis and pivoting around a tilting axis parallel to said transverse direction; a pivoting drive in said base connected to said support plate for pivoting said support plate around at least one of said canting axis and said tilting axis; and said lifting drive, said displacement drive and said pivoting drive being coupled together for pivoting said support plate around a predetermined isocenter of said support plate.
