A method for creating a therapy plan for a particle therapy, in which a filter is used to adjust the depth of penetration of the particle beam and an immobilization device is used to immobilize a body region of a patient to be treated, includes adjusting the geometry of a deformable mass of a filter to the geometry of the immobilization device. The deformable filter mass is applied, at least partially, to the immobilization device. A planning data record is obtained with recordings of the filter, so that the properties of the filter are determined on the basis of the recordings and are used in the therapy plan.

Method for creating a therapy plan

An x-ray computed tomography apparatus has a rotor on which are mounted at least one x-ray source and one detector. To avoid unwanted deformations of the rotor at high rotation speeds, the rotor is produced at least in segments from a fiber-reinforced composite material with a metal matrix.

A gantry for a computed tomography apparatus has a supporting body and a support ring for a rotatable rotary carriage. The supporting body internally exhibits a channel that communicates in terms of flow with the support ring. A cooling ring with a cooling channel is mounted on the radially-inward circumferential side of the support ring. The cross-section of the cooling channel varies in the circumferential direction. The cooling ring exhibits a cooling ring region that has stiffening ribs.
