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.
