    摘要: An x-ray and gamma-ray radiation energy imaging device has its semiconductor detector substrate and semiconductor readout/processing substrate both mounted on opposite sides of, and electrically communicating through, an intermediate substrate. The substrates are all substantially planar with the top plan perimeter of the semiconductor readout/processing substrate falling within the top plan shadow perimeter of the corresponding semiconductor detector substrate with which it electrically communicates. Additionally, all of the readout/processing circuitry contacts of the semiconductor readout/processing substrate are disposed on the surface of the semiconductor readout/processing substrate that electrically communicates with the intermediate substrate. Substantially all electrical communication to and from the semiconductor readout/processing substrate is routed through the intermediate substrate. The intermediate substrate is a printed circuit board or similar construct. The electrical contacts between the semiconductor substrates and the intermediate substrate are accomplished using bump-bonds, conductive adhesive bonds, conductive adhesive films or a combination thereof. One or two dimensional planar arrays of semiconductor readout/processing substrates and corresponding semiconductor detector substrates can be mounted on a single intermediate substrate using "tiling" techniques known in the art to form a mosaic radiation imaging device of increased active imaging area and reduced/minimized imaging dead area.

    摘要: Extra-oral dental x-ray imaging methods and systems are disclosed. An x-ray source exposes x-rays to an object to be imaged and an x-ray imaging device produces multiple frames during at least part of the exposure. The x-ray imaging device has an active area with a long dimension m and a short dimension n with m/n at least 1.5. A manipulator moves along a path the imaging device between consecutive radiated frames during exposure. The manipulator enables movement of the x-ray source and the imaging device by means of selective translation and rotation about at least one rotational axis located between a focal point of the x-ray source and the x-ray imaging device. An exposure profile program produces a substantially linear projection of at least part of said object to be imaged, said exposure profile program comprising at least one substantially linear section.

    摘要: A multi-functional dental extra-oral x-ray imaging system includes a conventional x-ray source and manipulator to control the movement of the x-ray source by translating and rotating, a real time multiple frame producing x-ray imaging device and at least two different exposure profile programs, whereas one of such profiles produces a standard panoramic image and a second of such profiles produces an angled or transverse slice to a the panoramic image. A third exposure profile program produces a substantially linear projection of the human skull by combining two linear projections, one for the right and one for the left part of the head. The sensor is a linear direct conversion operating preferably in the frame mode and producing more than l00fps.

    摘要: 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.
