PROBLEM TO BE SOLVED: To provide a medical image diagnostic apparatus which calculates a movement amount of a top board so as to locate a characterizing portion of a subject at an imaging position of imaging means and thereby makes the top board movable.SOLUTION: The medical image diagnostic apparatus includes: a bed having a top board on which a subject is placed a gantry including imaging means for collecting medical images of the subject an image acquisition part for acquiring optical images of the subject a position calculation part for acquiring three-dimensional position information on the characterizing portion of the subject on the basis of the optical images and a control part which, on the basis of the position information on the characterizing portion, calculates a movement amount of the top board so as to move the characterizing portion of the subject to an imaging position of imaging means, and moves the top board on the basis of the calculated movement amount.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】被検体の特徴部位が撮影手段の撮影位置にくるように天板の移動量を算出して、天板を移動可能にする医用画像診断装置を提供する。【解決手段】被検体を載置する天板を備えた寝台と、被検体の医用画像を収集する撮影手段を含むガントリと、被検体の光学画像を取得する画像取得部と、光学画像に基づいて、被検体の特徴部位の3次元的な位置情報を取得する位置算出部と、特徴部位の位置情報に基づいて、被検体の特徴部位が撮影手段の撮影位置に移動するように天板の移動量を算出し、算出した移動量に基づいて天板を移動させる制御部と、を備える。【選択図】図4
