Fuente: Wipo "digitalization" A digital X-ray imaging method includes: when a to-be-exposed body part is a stitching body part, determining an exposure parameter set of the stitching body part, the exposure parameter set includes multiple travel points that the X-ray source passes along at least two directions and exposure parameters of the X-ray source at the multiple travel points, the at least two directions being capable of determining a two-dimensional surface or a three-dimensional space; based on the exposure parameter set, controlling the X-ray source to pass the multiple travel points along the at least two directions and emit X-rays to the stitching body part at each travel point passed according to corresponding exposure parameters and controlling the detector to receive X-rays penetrating the stitching body part to obtain multiple digital X-ray images, and stitching the multiple digital X-ray images to obtain a radiograph of the stitching body part.
