A radiographic imaging assistance method by a radiographic imaging apparatus, comprising:
- capturing a radiographic image of a target part of a subject during a predetermined motion on a frame-by-frame basis;
- determining, on the frame-by-frame basis, whether or not a skeleton of the target part is at a reference position for the captured radiographic image, and identifying, as a reference position image, the radiographic image when the skeleton of the target part is at the reference position;
- and
- providing a notification based on whether or not the reference position image has been identified.
