摘要： In a method and a device for data transmission between two components moving relative to each other, a first of the components has a number of transmission segments arranged along the movement direction and a second of the components has receiver units arranged along the movement direction. The data to be transmitted are divided among several transmitter segments for parallel transmission thereof. The data to be transmitted are configured in respective data packets, each having a packet identifier in addition to a data portion. A receiver device connected to the receiver units assembles the respective data portions of the respective received packets in a correct sequence using the respective packet IDs. The need for a position detector for noting the relative position of the transmitter segments and the receiver units is avoided.

摘要： In a device for contact-free transmission of electrical signals between two gantry parts of a computed tomography system that rotate relative to one another, at least one annular, circumferential transmitter element is mounted on one gantry part to transmit the electrical signals, and at least one receiver element to receive the signals emitted by the transmitter element is mounted on the other gantry part. The transmitter element is formed by a single conductor running on a surface, this conductor representing an electrical reference ground (zero potential). At least one dielectric immediately follows on the surface, and multiple conductive conductor structure pairs are executed in two mirror-image parts and are mounted on the at least one dielectric. The separation of conductor structures arranged at the edge from the edge of the surface of the reference ground has a magnitude that both amounts to at least 10 mm and corresponds to at least half of the distance from the two conductor structures arranged in a mirror image at the edge, to the nearest conductor structure.

摘要： In a method and system for data and signal transfer between different sub-units of a medically-related system, in particular a CT system, digitized signals and digital data are transmitted together on a transmission line by means of serial multiplexing. The digitized signals and the digital data are transferred combined into individual packets having a length that is so small that the adherence to a predetermined updating rate of the signals is achieved. The expenditure for the wiring as well as for future expansions in medically-related systems can be significantly reduced.

摘要： An x-ray computed tomography apparatus has a stationary unit and a rotatable unit, carrying an x-ray source and a radiation detector. The rotatable unit rotates around an axis relative to the stationary unit, that proceeds through both units. In order to transmit signals and measured data between the rotating unit and the stationary unit, transmitting/reception devices are mounted at each unit. The transmitting/reception devices transmit directed signals and are automatically oriented toward each other during relative movement caused by rotation of the rotating unit with respect to the stationary unit.
