Apparatus, method, and program for producing subtraction images |
摘要 |
A plurality of past cross-sectional images are reconstructed from a plurality of past tomosynthesis images obtained by radiographing a subject by tomosynthesis. A plurality of current cross-sectional images are reconstructed from a plurality of current tomosynthesis images obtained by radiographing the subject by tomosynthesis. Each of the plurality of past cross-sectional images is superimposed on a corresponding current cross-sectional image included in the plurality of current cross-sectional images for each cross-sectional plane so as to align structural elements therein. When the structural elements are aligned, a subtraction image between the corresponding past cross-sectional image and current cross-sectional image is produced.
