Abstract: A method for synchronizing time in an Ethernet-based network having a master network subscriber and a slave network subscriber includes sending out a first telegram via the master network subscriber, where the slave subscriber receives the first telegram at a first receipt time value of a local system time and stores the first receipt time value. The method can also include reading out the first receipt time value via the master subscriber, sending out a second telegram by the master subscriber, where the slave subscriber receives the second telegram at a second receipt time value of the local system time and stores the second receipt time value, and reading out the second receipt time value via the master network subscriber. A speed parameter of the local system time can be calculated from the receipt time values via the master network subscriber, and transmitted to the slave subscriber.

Abstract: An operating device for a medical system for imaging and/or intervention is disclosed. In an embodiment, the operating device includes a housing; a grip region; a coupling unit; and a connecting unit. The connecting unit is configured to releasably connect to a holding structure for the operating device and, via the coupling unit, is coupled to the grip region such that a releasing of a releasable connection is caused by a gripping of the grip region with one hand of a person and an establishing of the releasable connection is caused by a letting go of the grip region. Further, the grip region is configured for carrying of the operating device by a gripping the grip region with one hand of the person.

Abstract: 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.

Abstract: In a method for detection of a stable installation of a system that has a rotation device mounted to rotate around a system axis and an arrangement for detection of measurement values indicative of oscillation of the rotation device, a statistical spread of the measurement values is calculated from N measurement values of different rotations of the rotation device, and the stable installation of the system is detected by a comparison of the calculated statistical spread with a predeterminable threshold. The detected N measurement values can be detected with a known arrangement for determination of an out-of-balance condition, so the method for detection of a stable installation can be implemented without the use of additional hardware components.

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.
