摘要： An X-ray image acquisition apparatus (15) includes a conversion panel (20) aligned with a photo detector array (40). The conversion panel (20) includes a plurality of conversion cells (22), each including a conversion body (31), an X-ray transparent and light reflective file over the top (32) of the body (31), and a light reflective film (36) surrounding the body (31). The body (31) is made of a scintillating material that efficiently generates optical light photons in response to X-ray radiation illuminating thereon and is substantially transparent to the optical light photons. The body (31) is also sufficiently long to absorb the X-ray radiation over a wide range of energy levels. The light reflective films (36, 38) collimate the optical light photons generated in the body (31) toward the photo detector array (40) to form X-ray images.

摘要： An apparatus and method for irradiating target objects, especially medical stents for in vivo implantation. A linear accelerator provides a high energy electron beam that impinges upon and is received by an x-ray conversion target. The x-ray conversion target is activated by either a static or dynamically moveable electron beam to generate and emit an x-ray flux so as to efficiently intercept the target object. The x-ray flux is directed to the target object for a desired time period and is of sufficiently high energy to efficiently impart radioactive properties to the target object. Alternatively, the target object is positioned within the path of the x-ray flux or is translated within the path during irradiation. Mechanical transport assemblies such as a carousel, rotational and/or linear translator and/or movement tube system also may be provided.

摘要： Systems and methods are provided for implementing an analytical approach to digital volumetric laminar tomography. The volumetric data visualizations generally take the form of volumetric images which approximate the spatial distribution of an x-ray attenuation coefficient throughout the region of interest in the object, such as a person, under examination. These visualizations are produced from a set of basic two dimensional data. One numerical technique employed in this regard takes the form of a process of convolution and back projection, where the convolution function is determined through the use of various analytic and empirical techniques.

摘要： In one example, a scanning unit for examining contents of a cargo container is disclosed comprising a first path through the scanning unit for transport of a cargo container and one or more sources of respective beams of radiation. At least one of the one or more sources are movable across a second path transverse to the first path. The second path extends partially around the first path. The scanning unit further comprises a detector extending partially around the first path. The detector is positioned to detect radiation interacting with the cargo container during scanning, such as radiation transmitted through the container. The at least one source and the detector are positioned so that the cargo container is transportable along the first path, between the source and the detector. A transport system may be provided to convey the object through the scanning unit, along the first path.
