Digital X-ray imaging method and apparatus

A method of digital X-ray imaging, comprising:

• configuring a current digital imaging mode in response to a mode configuring instruction, the current digital imaging mode comprising at least two of a first stitching mode, a second stitching mode and a third stitching mode, wherein the first stitching mode comprises radiographing a stitching body position along a direction of a coronal axis of an object under examination to obtain a plurality of digital X-ray images that are stitched to generate a radiograph of the stitching body position, the second stitching mode comprises radiographing the stitching body position along a direction of a sagittal axis of the object under examination to obtain a plurality of digital X-ray images that are stitched to generate the radiograph of the stitching body position, and the third stitching mode comprises radiographing the stitching body position along a direction of a vertical axis of the object under examination to obtain a plurality of digital X-ray images that are stitched to generate the radiograph of the stitching body position;
• when the current digital imaging mode is the first stitching mode:
• controlling an X-ray source to emit X-rays to the stitching body position of the object under examination to obtain the digital X-ray images in the direction of the coronal axis;
• and
• stitching the digital X-ray images along the direction of the coronal axis to obtain the radiograph of the stitching body position;
• when the current digital imaging mode is the second stitching mode:
• controlling the X-ray source to emit X-rays to the stitching body position of the object under examination to obtain the digital X-ray images in the direction of the sagittal axis;
