Summary:To provide a technique capable of avoiding contact between a subject to be examined and a gantry.SOLUTION: A CT apparatus comprises: a sensor section 19 outputting distance data for determining a distance between the sensor section 19 and at least part of a subject to be examined laid on a cradle 41; contour-data generating means for generating contour data representing a contour of the at least part of the subject to be examined on the basis of the distance data obtained from the sensor section 19; and determination means for determining whether or not there is a risk of the subject to be examined coming into contact with a gantry while the gantry or table is moving, on the basis of data representing a limit of a range up to which the subject to be examined can come close to the gantry and on the basis of the contour data.SELECTED DRAWING: Figure 15 【課題】被検体とガントリとの接触を回避することができる技術を提供する。【解決手段】CT装置は、センサ部19を有している。センサ部19は、センサ部19とクレードル41に載置された被検体の少なくとも一部分との間の距離を求めるための距離データを出力する。また、CT装置は、センサ部19から得られた距離データに基づいて、被検体の少なくとも一部分の外形を表す外形データを生成する外形データ生成手段と、ガントリに対して前記被検体が近接可能な範囲の限界を表すデータと前記外形データとに基づいて、前記ガントリ又は前記テーブルが動いている間に前記被検体が前記ガントリに接触する恐れがあるか否かを判定する判定手段とを有している。【選択図】図15
