In an adjustment device and method for a
tomography apparatus for aligning of a
patient support device and an acquisition
system relative to one another, a reference
laser projects onto a reference element associated with the
patient support device, the reference
laser being directly associated with a rotary frame of the acquisition
system, such that tolerances in the alignment between the reference
laser and the acquisition
system are prevented. Moreover, due to the arrangement of the reference laser directly on the rotary frame of the
tomography apparatus, a simple calibration between laser beam and the acquisition plane of the acquisition system is ensured by a displacement of the reference laser in two different rotation angle positions which exhibit an angular interval therebetween of substantially 180 degrees.
