摘要： The present invention relates to signal and power supply transmission for an X-ray source. In order to provided an improved signal and power supply transmission with reduced constructional complexity and enhanced operation possibilities, an integrated signal and power supply transmission arrangement is provided, comprising a supply board (12), a main board (14), an insulating plate (16), at least one transformer arrangement (18), and at least one signal transmission arrangement (20). The insulating plate is provided between the supply and the main board. The transformer arrangement is provided to supply electric energy to the driving circuit of a transistor, which in turn feeds an X-ray source. The transformer arrangement comprises a primary electric conductor arranged on the supply board to cause electromagnetic induction in a secondary electric conductor arranged on the main board. The signal transmission arrangement is adapted to transmit a signal between the supply board and the main board; wherein the signal transmission arrangement comprises at least a first optical signal transmission device provided on the supply board, and a second optical signal transmission device (30) provided on the main board. The insulating plate is light-transmissive at least in the part between the first and second optical signal transmission device. The first and the second optical signal transmission devices are arranged in an optical connection path.

摘要： A controller for controlling the dose rate (exposure kV tube voltage) of an X- ray system, in which the actual dose rate is measured and compared with an optimal dose rate, and the resultant difference value is fed to a module (20) (e.g. a PID module) which is arranged to adjust the dose rate (by adjusting the exposure kV voltage) so as to minimise the difference value. No preset parameters are required to be entered prior to exposure.

摘要： The invention relates to a method of controlling the exposure of an X-ray image. Starting values for the tube current, the tube voltage and the exposure duration are hereby set on the X-ray tube (10). Following the start of the exposure, the resultant dose rate is measured by a sensor (30, 31) and made available to a control system (100, 200, 300). In order to achieve a predetermined dose for the X-ray image, the control system adjusts the following variables in succession: the tube current within a current range; if applicable, the exposure duration within a time slot; the tube voltage within a voltage range; the exposure duration within the time slot. A rapid controlling of the tube current is enabled, preferably by the pulse-width modulation of the counter-voltage at the control grid of the X-ray tube.
