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.

摘要： A linear track scanning imaging system and method, the imaging system comprising: a ray generating unit comprising a plurality of ray sources, where the plurality of ray sources emit beams alternately and only one ray source emits a beam at a same time; an actuating means for causing an object under examination to perform a relative movement with respect to the linear track scanning system along a linear track, thereby leading the object under examination to pass through the scanning area of the linear track scanning imaging system; a data collecting unit which collects the projection data of the object under examination for each ray source respectively; an imaging unit which reconstructs an image of the object under examination based on the projection data collected for each ray source; and a display unit for displaying the reconstructed image. By adopting a plurality of ray sources arranged according to a certain spatial distribution and emitting beams alternately according to a certain time sequence, it is possible to achieve a larger scanning viewing angle with a shorter detector length, thereby reducing the number of the detector units required by the system and shortening the total scanning distance of the examined object.
