PROBLEM TO BE SOLVED: To provide an image diagnostic device which can prevent interference between a mounting board and a radiation detector as a precision machine from being caused by a deformation of the mounting board due to the weight of a sample on the mounting board.SOLUTION: An image diagnostic device 100 sets the uppermost end position PH, which is the closest position to the lower surface 11c of a mounting board 11 in the moving range in the vertical direction of a radiation detector 13 according to the height position of the lower surface of the mounting board on which a sample 1 detected by a contact sensor 15 is being placed.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】載置された被検体の重みによる載置台の変形に起因して載置台と精密機器である放射線検出部とが干渉するのを抑制することが可能な画像診断装置を提供する。【解決手段】画像診断装置１００は、接触センサ１５によって検出された被検体１が載置された状態の載置台１１の下面１１ｃの高さ位置に基づいて、放射線検出部１３の鉛直方向の移動範囲における載置台の下面に対して最も近づく最上端位置ＰＨを設定するように構成される。【選択図】図３
