摘要： Disclosed are a method and a device for inspection of drugs concealed in liquid articles without opening the outer packages. The method comprises the steps of: emitting radiation beams to transmit through the liquid article; receiving the radiation beams transmitted through the liquid article to get multi-angle projection data; inversely operating the multi-angle projection data based on the uniformity of the liquid article to obtain an attribute value of the inspected liquid article; retrieving a reference attribute value in a pre-created database by using the identification information of the liquid article as an index, and calculating a difference between the calculated attribute value and the reference attribute value; and determining whether the difference is larger than a predefined threshold value; wherein it is concluded that there are drugs concealed in the liquid article when the difference is determined to be larger than the predefined threshold value.

摘要： An image processing method, an image processing device and a storage medium are disclosed. The image processing method includes processing input projection domain data using a convolutional neural network. The neural network includes a projection domain network, an analytical reconstruction network layer and an image domain network. The projection domain network may process the projection domain data to recover possible missing data, thereby improving quality of the projection. The image domain network processes a reconstructed image to obtain an estimated image. The image domain network is adjusted by using an a priori model cost function based on the estimated image, and back propagation of a gradient is performed through the analytical reconstruction network layer to adjust parameters of a convolutional kernel of the projection domain network. A projection operation is performed on the estimated image by using a system projection matrix of the CT scanning system to obtain a projection result.
