    • An X-ray detector is provided to prevent cross-talk by filling a gas in the closed space of the body and to reduce the manufacturing cost by not using thin film transistor. An X-ray detector comprises a body including a closed space, and three electrodes formed in the body. The body comprises a supporting part(130) which supports top and lower substrates(110,120) installed opposite to each other. A gas is filled in the closed space of the body. The electrodes include fist and second electrodes(150a,150b) formed on the upper and lower substrates to intersect each other and a third electrode(150c) formed on the inside or outside of the lower substrate.
    • 提供了一种X射线检测器,以通过将气体填充到身体的封闭空间来防止串扰,并且通过不使用薄膜晶体管来降低制造成本。 X射线检测器包括具有闭合空间的主体和形成在主体中的三个电极。 主体包括支撑部件(130),该支撑部件支撑彼此相对安装的顶部和底部基板(110,120)。 气体填充在身体的封闭空间中。 电极包括形成在上基板和下基板上彼此相交的第一和第二电极(150a,150b)和形成在下基板的内部或外部的第三电极(150c)。

    • A multi-layer dental panoramic and transversal x-ray imaging system includes an x-ray source; a digital imaging device capable of frame mode output with a sufficient frame rate; a mechanical manipulator having at least one rotational axis located in a position other than the focal point of the x-ray source; a position detection mechanism for detecting the camera position in 1D, 2D or 3D depending of the complexity of the trajectory; a final image reconstruction mechanism for reconstructing the final images out of the stored frames; a real time storage system such as RAM, hard drive or an drive array able to store all the frames captured during an exposure; and a digital processing unit capable of executing the reconstruction algorithm, such components being interconnected in operational arrangement. The system produces selectively dental panoramic x-ray images, dental transversal x-ray images and dental tomosynthetic 3D images from a frame stream produced by a high-speed, x-ray digital imaging device.
    • 多层牙科全景和横向X射线成像系统包括x射线源; 能够以足够的帧速率输出帧模式的数字成像装置; 机械操纵器,其具有至少一个位于除x射线源的焦点之外的位置的旋转轴; 位置检测机构,用于根据轨迹的复杂度来检测1D,2D或3D中的相机位置; 用于从存储的帧重建最终图像的最终图像重建机构; 诸如RAM,硬盘驱动器或能够存储在曝光期间捕获的所有帧的驱动器阵列的实时存储系统; 以及能够执行重建算法的数字处理单元,这些组件以操作布置相互连接。 该系统从由高速x射线数字成像装置产生的帧流中选择性地生成牙齿全景X射线图像,牙科横向X射线图像和牙科合成3D图像。
