Fuente: Wipo "digitalization" Disclosed are a digital X-ray imaging method and a digital X-ray imaging apparatus (01), comprising: when a to-be-exposed body part is a stitching body part, determining an exposure parameter set of the stitching body part, said exposure parameter set comprising a plurality of travel points that the X-ray source (10) passes along at least two directions and exposure parameters of the the X-ray source (10) at the multiple travel points, said at least two directions being capable of determining a two-dimensional surface or a three-dimensional space, then based on the exposure parameter set, controlling the X-ray source (10) to pass the multiple travel points along the at least two directions and emit X-rays to the stitching body part at each of the travel points passed according to exposure parameters corresponding thereto and controlling the detector (20) to receive X-rays penetrating the stitching body part to obtain a plurality of digital X-ray images, and stitching the plurality of digital X-ray images to obtain a radiograph of the stitching body part. Accordingly, exposure and stitching of the stitching body part can be implemented through the present disclosure.
