1. An image processing apparatus comprising at least one processor,
the at least one processor being configured to:
acquire a two-dimensional radiographic image of a subject including a bone tissue;
derive a bone mass in a bone part region of the subject based on the two-dimensional radiographic image;
acquire a plurality of two-dimensional medical images, each of which represents a state of a trabecula and is different from the two-dimensional radiographic image; and
based on the bone mass that has been derived, subdivide the bone part region of the two-dimensional radiographic image into a plurality of stage regions associated with a plurality of stages of the bone mass, and for each of the plurality of stage regions, select, from the plurality of two-dimensional medical images, a two-dimensional medical image representing the state of the trabecula corresponding to the stage of the bone mass associated with each of the plurality of stage regions, and apply the selected two-dimensional medical image to each of the plurality of stage regions to generate a two-dimensional trabecula image representing a trabecula of the bone tissue.
