    摘要： An image processing method, comprising: acquiring, by a CT scanning system, projection data of an object; and processing, by using a convolutional neural network, the projection data, to acquire an estimated image of the object. The convolutional neural network comprises: a projection domain network for processing input projection data to obtain estimated projection data; an analytical reconstruction network layer for performing analytical reconstruction to obtain a reconstructed image; an image domain network for processing the reconstructed image to obtain an estimated image, a projection layer for performing a projection operation by using a system projection matrix of the CT scanning system, to obtain a projection result of the estimated image; and a statistical model layer for determining consistency among the input projection data, the estimated projection data, and the projection result of the estimated image based on a statistical model.

    摘要： A fork-arm lift tractor includes a vehicle body, a supporting plate disposed above the vehicle body, a lifting device for driving the supporting plate to be lifted, a front and rear fork-arm assemblies, a front and rear fork-arm drive assemblies. The front fork-arm assembly includes two front fork-arms rotatably disposed at the supporting plate. The rear fork-arm assembly includes two rear fork-arms rotatably disposed at the supporting plate, and the front and rear fork-arms may be deployed or retracted from both sides of the supporting plate. The front fork-arm driving assembly includes a front transmission part, and a front power device disposed at the supporting plate and may drive the front transmission part to move horizontally linearly so as to rotate the two front fork-arms. The rear fork-arm driving assembly has almost the same structure of the front fork-arm driving assembly and is used to rotate the two rear fork-arms.

    摘要： The present disclosure discloses a detector device comprising a plurality of detector assemblies. Each detector assembly comprises at least one detection crystal units having a first energy response and those having a second energy response, which are both arranged along a first direction at intervals, each detection crystal unit having a first/second energy response including at least one detection crystals having a first/second energy response arranged along a second direction. The at least one detection crystal units having a first energy response and the at least one detection crystal units having a second energy response are, at least partially, alternatively arranged along the first direction when viewed from an incidence direction of the X-ray. The present disclosure also discloses a dual energy CT system having the detector device and a CT detection method using this system.

    摘要： The present disclosure provides methods and devices for locating a plurality of interested objects in CT imaging. Location of the interested objects in the three-dimensional space can be determined by using three projection images that are substantially perpendicular to each other. The method can rapidly locate interested objects in a CT image without pre-reconstruction of the CT image even if there are a plurality of interested objects in the field of view. The algorithm does not involve interactive steps. The method is rapid and effective, and thus applicable to industrial applications.
