Abstract: A gantry for a computed tomography apparatus has a rotary carriage that is rotatable around an axis and a support ring arranged around the rotary carriage with a circumferential cooling channel. The support ring has a number of openings distributed around its circumference and forming a non-uniform opening pattern. The rotary carriage likewise has inflow and outflow openings that, in operation, overlap the openings on the stationary part of the computed tomography apparatus such that a coolant flows through between the support ring and the rotary carriage. A steady pressure fluctuation that leads to a reduction of the noise stress in operation ensues thanks to the non-uniform opening pattern.

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.
