摘要： To comply with radiation protection provisions that differ from one another for different operating functions without operational restrictions, a radiation protection system is provided in the case of a multifunctional x-ray system for a solid state detector assigned to the x-ray system. The radiation protection system includes a device for restricting the current outer contours of an x-radiation field to bounding outer contours dependent on the selected operating function of the x-ray system.

摘要： A radiation imaging apparatus is capable of taking a moving picture by acquisition by a reading circuit of a plurality of radiation image signals on the basis of a plurality of successive times of irradiation of a radiation detector with radiation rays. The radiation detector has a two-dimensional array of pixels. In a period between a start of an n-th time of irradiation with radiation rays and a start of an (n+1)-th time of irradiation with radiation rays, where n is a natural number, a controller switches an operation status of an analog-to-digital converter that converts electric signals read by the reading circuit into digital signals so that power consumption of the analog-to-digital converter is reduced.

摘要： The invention relates to a residual-current circuit breaker for an X-ray device. In one embodiment, the residual-current circuit breaker comprises at least one input, via which a detector identification signal of a detector identification element can be received, said signal characterizing the presence of an X-ray detector and at least one input, via which a selection signal for an exposure measurement element can be received, said signal characterizing the activation of an exposure measurement element. A deactivation signal can be issued via at least one output of the residual-current breaker, the deactivation signal being generated as long as a detector identification signal and a selection signal that is assigned to the same detector as the detector identification signal are not received at the same time.

摘要： An x-ray examination apparatus comprises an x-ray source and an x-ray detector. The x-ray detector includes a photoconductor to derive electric charges from incident x-radiation and read-out elements which derive electrical pixel-signals from the electric charges from the photoconductor. A central group of the read-out elements is located in a central region of the x-ray detector and a peripheral group of the read-out elements is located in a peripheral region which surrounds the central region. The x-ray examination apparatus being provided with a selection system to select the central group of read-out elements so as to supply pixel-signals from the central group of read-elements to the output circuit. The selection system may include an encompassing electrode to drain electric charges from the peripheral group. Or the selection system shields the peripheral group from x-rays.

摘要： A nonintrusive inspection apparatus is described of the kind having a base frame, an elongated shield on the base frame, a conveyor belt passing through the shield which is used for transporting closed containers, and a rotating CT scanner subsystem which is used for scanning the container on the conveyor belt. The CT scanner subsystem is mounted through the shield to the base frame. The shield provides sufficient rigidity for the CT scanner subsystem. A cover is positioned over the CT scanner subsystem, but only over a portion of the shield, thereby allowing for a person on one side of the shield to see a person on an opposite side of the shield.
