Abstract: The invention relates to an array of sensor elements, wherein the sensor elements are provided to detect electromagnetic radiation such as X-radiation or light, and in doing so to generate a charge signal corresponding to the intensity of the radiation. A sensor element further comprises means enabling the incoming dose of radiation to be determined. In the array, the sensor elements form groups, so that the outputs of all sensor elements of a group are coupled. This on the one hand enables a determination of the dose in these areas, and on the other hand enables images to be formed with a lower resolution in a simple manner, by the combining of output signals from several sensor elements. Furthermore, the sensor elements of one group are preferably arranged "isolated" in such a way that they are surrounded by sensor elements of other groups. Such an array can be used, for example, in an X-ray diagnostic facility or in an optical image recording system.

Abstract: The invention relates to a method and a device for automatic testing of an X-ray system ( 2 ). The doors ( 5 a, 5 b) leading to the room ( 1 ) in which the X-ray system ( 2 ) is installed are monitored by way of sensors ( 4 a, 4 b). Furthermore, the state of the room ( 1 ) can be monitored by means of further sensors such as video cameras ( 3 ). Automatic testing of the X-ray system ( 2 ) while utilizing X-rays is started only if and for as long as all doors are closed and the other sensors do not indicate that a safe state is abandoned. The device may also include facilities for automatically positioning a phantom in the beam path. Such facilities may in that case include a phantom which is provided on a flexible foil.

Abstract translation: 本发明涉及传感器元件的阵列，其中提供传感器元件以检测诸如X射线或光的电磁辐射，并且这样做以产生对应于辐射强度的电荷信号。 传感器元件还包括能够确定入射剂量的辐射的装置。 在阵列中，传感器元件形成组，使得组中的所有传感器元件的输出被耦合。 这一方面能够确定这些区域中的剂量，另一方面通过组合来自多个传感器元件的输出信号，能够以简单的方式以更低的分辨率形成图像。 此外，一组的传感器元件优选地被布置成“隔离”，使得它们被其他组的传感器元件包围。 这种阵列可以用于例如X射线诊断设备或光学图像记录系统中。

Abstract: The invention relates to magnetic tracking system that is particularly adapted for a combination with an imaging system, for example with a rotational X-ray device (10). The magnetic tracking system comprises pairs of first (21a, 22a, 23a) and second (21b, 22b, 23b) field generators that are disposed on opposite sides of a measuring volume (V). The first field generators may particularly be attached to the radiation source (13) and the second field generators (21b, 22b, 23b) to the detector (11) of an X-ray device. Moreover, the first and second field generators may be constituted by coils with opposite magnetic polarity. Due to the attachment of the field generators to the X-ray device, motions of the X-ray device do not disturb the magnetic field (B) in a frame of reference fixed to the imaging system.
