Abstract: 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.

Abstract: A reference body for alignment of laser projectors and an acquisition system of a tomography apparatus relative to one another, has at least two reference indicators, with each reference indicator establishing a reference plane. Each reference plane serves for alignment of one of the laser projectors. The at least two reference indicators enable the simultaneous alignment of laser projectors without a shifting of the reference body being necessary.
