PROBLEM TO BE SOLVED: To provide a medical image processor which automatically form a suitable image to read the image of spine (especially a vertebral body and vertebral foramen) and display the image.SOLUTION: A medical image processor 1 calculates a straight line L which extends to the anteroposterior direction of a subject and passes through a vertebral foramen 4 to each tomographic image (S2), calculates Y coordinates Ya, Yb at the end points of the vertebral body 3 on the straight line L (S3), calculates a point α which externally divides the line between two end points of the vertebral body 3 positioned at the ventral side on the straight line L (S4), calculates a point β which externally divides the line between two end points of the vertebral body 3 positioned at the back side on the straight line L (S5), calculates the central point γ between α and β (S6), calculates a base line Lα passing through all the points α, a base line Lβ passing through all the points β, and a base line Lγ passing through all the points γ (S9), and uses any of base lines Lα, Lβ, Lγ to form a vertebral image (S10).COPYRIGHT: (C)2013,JPO&INPIT【課題】脊椎(特に椎体や椎孔)を読影するために好適な画像を自動的に作成し、表示する医用画像処理装置等を提供する。【解決手段】医用画像処理装置1は、各断層像に対して、被検体の前後方向に延伸し、椎孔4を通る直線Lを算出し(S2)、直線L上における椎体3の端点のY座標Ya、Ybを算出し(S3)、直線L上における腹側に位置する、椎体3の2つの端点間を外分する点αを算出し(S4)、直線L上における背側に位置する、椎体3の2つの端点間を外分する点βを算出し(S5)、α及びβの中点γを算出し(S6)、全てのαを通る基準線Lα、全てのβを通る基準線Lβ、全てのγを通る基準線Lγ、を算出し(S9)、基準線Lα、Lβ、Lγのいずれかを用いて、脊椎画像を作成する(S10)。【選択図】図2
