Abstract: A container for detecting includes a bottom (12) and a side wall (11), one side of which couples with the bottom so as to form a space, wherein single or plural protrudings (12A, 12B, 12C) are provided on a lower surface of the bottom. The container for detecting also inludes a dividing part for dividing the space into multiple subspaces.

Abstract: A method for inspecting the drug concealed in a liquid article comprises the steps of: emitting a radiation beam to transmit through the liquid article (20); receiving the radiation beam transmitted through the liquid article (20) to form a multi-angle projection data; calculating a property value of the liquid article (20) by the inverse operation of the multi-angle projection data, based on the uniformity of the liquid article (20); using the identification information of the liquid article (20) as an index to search the reference property value from preset database and calculating the difference between the calculated property value and the reference property value; and judging whether said difference is larger than the predetermined threshold value. When said difference is larger than a predetermined threshold value it is believed that said liquid article conceals drug.

Abstract: A device for rapid imaging and inspecting of a moving target comprises a channel to pass the moving target; a scanning and imaging means to transmit radiation beams to the moving target passing through the channel for imaging and inspecting of the moving target; the first inspecting unit to estimate whether the moving target enters into the channel and to counter the number of the moving target in the channel; the second inspecting unit to measure the moving velocity of the moving target in the channel; and a control unit to control the second inspecting unit for inspecting the moving velocity of the moving target according to the inspected signal, obtained from the first inspecting unit, that the target enters into the channel, and to control the scanning and imaging means according to the measured results of the second inspecting unit, in order that the scanning and imaging means produces radiation beams at the frequency corresponding to the moving velocity of the moving target for inspecting the moving target.

Abstract: A detector array includes the first line array detector and the second line array detector. The first line array detector is used to detect the first ray and the second redial which penetrate through the first multi-part of the detected object, and the first detecting data and the second detecting data corresponding to the first multi-part are acquired. The first ray and the second redial are sent alternately. The first line array detector is positioned parallel to the second line array detector, which is used to detect the first ray and the second redial which penetrate through the second multi-part of the detected object for acquiring the third detecting data and the forth detecting data corresponding to the second multi-part. The first multi-part and the second multi-part are the same partly. The use of said detector array can enhance the scan detecting efficiency of alternative dual-energy ray for detected object and the accuracy of identifying material.
