A detector apparatus for use as part of a data network includes a plurality of x-ray detectors, each of the plurality of x-ray detectors including a network-capable network interface, and a switch or router, connected to each of the network-capable network interfaces of the plurality of x-ray detectors, each of the plurality of x-ray detectors including a distinct IP address such that the data network is adjustable to take a change in a number of the plurality of x-ray detectors into account. The plurality of x-ray detectors are configured to detect x-rays generated from a single x-ray source.

Data transfer between an x-ray detector and an arithmetic unit via a network protocol

A method is disclosed for operating an x-ray device, in particular a computed tomograph, including a controller and a number of detector units coupled thereto for signaling purposes. Each of the detectors includes a functional unit and a number of detector elements coupled thereto. In an embodiment of the method, a synchronized clock signal for activating the detector elements is created from a control signal of the controller on the functional unit side.

Method for operating an x-ray device and associated x-ray device

A detector apparatus includes at least one x-ray detector, including a network-capable network unit; and a switching unit connected to the network unit of the x-ray detector.

A detector facility for a medical imaging system is described. The detector facility has a plurality of individual detectors and at least one detector controller. The detector facility is embodied such that it can be switched to at least one power-saving mode, in which at least one portion of the components of the individual detectors is deactivated and concurrently at least one portion of the components of the detector controller is not deactivated. A medical imaging system, in particular a computed tomography system, having such a detector facility; and a corresponding method for operating a detector facility of a medical imaging system are also described.

Operation of a detector facility

A device is for the spatially resolved measurement of photons, in particular x-ray photons. In an embodiment, the device includes a first plurality of photoelectric converters, a second plurality of current measuring apparatuses and a third plurality of voltage conditioners. Each current measuring apparatus is electrically connected to at least one photoelectric converter; each voltage conditioner is electrically connected to at least one current measuring apparatus; and each photoelectric converter is configured to generate a photocurrent from an incident photon. Each voltage conditioner is connectable to a supply bar, configured to provide a supply voltage. The voltage conditioner is configured to down-convert the supply voltage to an operating voltage of a current measuring apparatus. Each current measuring apparatus is configured to measure a photocurrent under operating voltage when this is generated in a photoelectric converter, electrically connected to the respective current measuring apparatus.

An X-ray device according to an embodiment of the invention includes an X-ray detector including a number of detector elements, the detector elements being subdivided into at least two subgroups, each of spatially linked detector elements. The X-ray device or the X-ray detector includes a voltage supply unit for providing a fundamental voltage. The X-ray detector includes two voltage transformers, of which each is associated with respectively one of the two subgroups. And each of the voltage transformers is configured for converting the fundamental voltage into a detector operating voltage for the detector elements, which is lower than the fundamental voltage.

A method is disclosed for transmission of register contents of a CT detector with hierarchical hardware structure, wherein the first hierarchy level is formed by a control unit containing a register table for the read-out register contents of FPGAs lying lower down in the hierarchy and an intermediate register store for register contents to be written. With each new reading, the new register contents for FPGAs lying lower down in the hierarchy arriving during the respective preceding reading from the central control at the control unit are forwarded to the next hierarchy level. With each new reading, the register contents of all FPGAs lying lower down in the hierarchy are re-entered into the register table of the control unit. Finally, in the event of a readout command transferred asynchronously from the central control, the register contents are read out exclusively from the register table.
