PROBLEM TO BE SOLVED: To easily perform the comparison between this measurement result of bone-salt quantity determination and the past measurement result and cause clarification when this measurement result largely differs from the past measurement result.SOLUTION: According to a medical image processor 3, a control part 31 creates a graph indicating the aging effect of bone-salt quantity determination based on this measurement result of the bone-salt quantity determination and the past measurement result of the same patient stored in a storage part 33, and displays the created graph and a medical image of this measurement source of the bone-salt quantity determination side by side on a display part 35.COPYRIGHT: (C)2013,JPO&INPIT【課題】今回の骨塩定量の計測結果と過去の計測結果との比較及び今回の計測結果が過去の計測結果と大きく異なる場合の原因解明を容易に行えるようにする。【解決手段】医用画像処理装置3によれば、制御部31は、今回の骨塩定量の計測結果及び記憶部33に記憶されている同一患者の過去の計測結果に基づいて、骨塩定量の経時変化を示すグラフを作成し、作成されたグラフと今回の骨塩定量の計測元の医用画像とを並べて表示部35に表示する。【選択図】図13
