Abstract: A system for inspecting an object, includes: a source of X-ray radiation; a horizontal array of detectors, wherein the source and the array of detectors are positioned substantially on a first plane; a platform configured to rotate as well as translate in a vertical trajectory, wherein the platform is positioned on a second plane between the source and the array of detectors, and wherein the object is disposed on the platform; and a computing device configured to: cause the source to fire a substantially horizontal fan beam in a third plane, wherein the third plane is above a top of the object; acquire calibration data from the array of detectors while the third plane is above the top of the object; cause the platform to simultaneously rotate and raise the object vertically upwards; acquire scan data of the object; and generate a three dimensional scan image of the object.

Abstract: An apparatus and method for quick imaging and inspection of a moving target. The apparatus comprises a passage, a scanning and imaging device (106), a first position sensor (101), a second position sensor (103), and a control unit (105). The control unit (105) powers on an electron induction accelerator in the scanning and imaging device (106) to make the electron induction accelerator enter a standby state when the control unit (105) receives from the first position sensor (101) a detection signal indicating that a moving target (100) enters the passage, and controls a beam emitting time point and a beam emitting mode of the electron induction accelerator to correspondingly inspect different parts of the moving target (100) when the second position sensor (103) detects that different sections pass through a radiation scanning area. The driver and passengers do not need to get off when a traveling vehicle is inspected, the apparatus controls the accelerator to emit ray beams with corresponding energy to perform scanning when the moving target passes through the scanning area, flexible scanning is realized, and inspection time is reduced.

Abstract: An x-ray computer tomograph, having an x-ray source that generates a fan beam of x radiation and having a two-dimensional energy-resolving detector array, both of which are situated on opposite sides of a gantry so that the x-ray radiation passes completely through a test region. A row of detector elements is situated in the plane of the fan beam and is adjoined in at least one direction perpendicular to the fan beam by several additional rows of detector elements. During the measurement, no secondary collimator is positioned between the test region and the detector array. The following equation applies for the width (B) of the detector elements: B=ZP*arc sin(qmax*λ), where qmax is a pulse transmission, λ is a wavelength of the x radiation, and ZP is the distance of the measurement point from the detector.
