The embodiment of the invention discloses a method and device for removing a grid shadow in an X-ray image and a storage medium. The method comprises the following steps: acquiring an X-ray image; converting the X-ray image into a predetermined resolution; inputting the X-ray image converted into the predetermined resolution into an artificial neural network adapted to detect a grid shadow of a grid, wherein an input layer of the artificial neural network corresponds to the predetermined resolution; and when the artificial neural network determines that the X-ray image converted into the predetermined resolution includes a grid shadow, performing grid shadow removal processing on the X-ray image. According to the embodiment of the invention, whether the grid shadow exists in the X-ray image is determined based on machine learning, fast Fourier transform does not need to be executed, and the processing time is saved. Moreover, the embodiment of the invention is suitable for the X-ray imaging system supporting
