PROBLEM TO BE SOLVED: To finally obtain a valid measurement result of bone-salt quantity determination.SOLUTION: A medical image processor 3 includes: a display part 35 displaying an image based on image data obtained by performing X-ray radiography of the left hand of a subject by a modality 2 an operation part 34 designating prescribed two points of a left-hand second metacarpal bone B in an image displayed on the display part 35 a CPU (Central Processing Unit) 31a (a measurement part) measuring a bone-salt quantity based on the coordinates of the two points designated by the image data and the operation part 34 and a storage part 33 storing the image data and the measurement result of the measured bone-salt quantity. The distance between the two points is included in the measurement result, and the CPU 31a decides whether or not the difference between the measured distance between the two points and the distance between the two points of the same subject stored in the storage part 33 exceeds a prescribed range, and when it is decided that the difference exceeds the prescribed range, notifies prescribed warning information K.COPYRIGHT: (C)2013,JPO&INPIT【課題】最終的に妥当性のある骨塩定量の計測結果を得る。【解決手段】モダリティ2により被験者の左手をX線撮影して得られた画像データに基づく画像を表示する表示部35と、表示部35に表示された画像中の左手第二中手骨Bの所定の二点を指定する操作部34と、画像データと操作部34により指定された二点の座標とに基づいて骨塩量を計測するCPU31a(計測部)と、画像データ及び計測された骨塩量の計測結果を記憶する記憶部33と、を備えた医用画像処理装置3であって、計測結果には二点間の距離が含まれ、CPU31aは、計測された二点間の距離と、同一の被験者の記憶部33に記憶された二点間の距離との差が所定の範囲を越えるか否かを判定し、差が所定の範囲を越えると判定された場合に、所定の警告情報Kを報知する。【選択図】図2
