    • A time switch device for X-ray diagnostic apparatus, in particular for the preparation of tooth or dental exposures, including a knob for the setting of the exposure periods and which has a time scale on a scale carrier associated therewith. The knob has associated therewith a symbol carrier which, in the displacement direction of the knob, is adjustable relative to the knob and to the time scale, on which there are drawn the symbols of the objects which are to be X-rayed at such a spacing relative to each other whereby, upon the setting of one symbol on the exposure period associated therewith, the other symbols are then located opposite to the exposure periods which are associated therewith.
    • 一种用于X射线诊断装置的时间开关装置,特别是用于制备牙齿或牙齿暴露的时间开关装置,包括用于设定曝光时段的旋钮,并且在与其相关联的刻度尺上具有时间刻度。 旋钮具有与其相关联的符号载体,该符号载体在旋钮的位移方向上相对于旋钮和时间尺度是可调节的,在该刻度上绘制将被X射线照射的物体的符号 相对于彼此的间隔,由此,在与其相关联的曝光周期设置一个符号时,其它符号然后与与其相关联的曝光周期定位。

    • An x-ray source, whose output is collimated into a thin fan-shaped beam, and detector means spaced from the source are mounted for scanning and orbiting jointly about a body in a partial or complete revolution and x-ray intensities to provide data for reconstructing an image. The detector and source combination and the body are moved relative to each other in an axial direction for scanning the body layers in sequence. In one embodiment the x-ray source is pulsed as it scans and in another the fan-shaped beam is on continuously and readout is done sequentially so in either case a large number of intensities for each layer are obtained. A high precision encoder system is used to synchronize x-ray pulses and readouts spatially and with line frequency. Means are provided for storing the cables which lead to the rotatable source, and the detectors and other moveable components. An embodiment for scanning a body part such as a breast has means for conditioning and controlling water in which the part is immersed.
    • 其输出准直成薄扇形光束的X射线源和与源间隔开的检测器装置被安装用于以局部或完整的旋转和x射线强度在身体周围共同扫描和绕动,以提供数据用于 重建图像 检测器和源组合和主体相对于彼此沿轴向移动以依次扫描体层。 在一个实施例中,x射线源在其扫描时被脉冲,并且在另一个扇形光束连续打开,并且顺序地进行读出,因此在任一情况下,获得每层的大量强度。 高精度编码器系统用于在空间上和线路频率上同步x射线脉冲和读数。 提供用于存储通向可旋转源的电缆以及检测器和其它可移动部件的装置。 用于扫描诸如乳房的身体部位的实施例具有用于调节和控制部件被浸入的水的装置。
