Description

前述した目的を達成するために本発明は、撮影空間となる開口部を備えたガントリと、前記ガントリを所定のチルト角度に傾斜させるチルト駆動部と、前記ガントリに固定され、撮影位置から所定の基準距離だけ離れた位置に位置決め用のガイド光を照射する投光器と、被検体を載置する天板を備え、該天板を前記ガントリに設けられる開口部内の所定位置に搬送する寝台と、を備えた医用画像撮影装置であって、前記チルト駆動部により前記ガントリが傾斜された状態で前記投光器を用いて目的部位を位置決めした後に、前記目的部位が前記撮影位置に到達するように、前記寝台の天板の位置を移動させる移動手段を備えることを特徴とする医用画像撮影装置である。 In order to achieve the above-described object, the present invention provides a gantry having an opening serving as an imaging space, a tilt driving unit that tilts the gantry at a predetermined tilt angle, and is fixed to the gantry and is A projector that irradiates a guide light for positioning at a position separated by a reference distance; and a bed that includes a top plate on which the subject is placed and transports the top plate to a predetermined position in an opening provided in the gantry A medical image photographing apparatus provided, wherein the bed is positioned so that the target part reaches the photographing position after the target part is positioned using the projector in a state where the gantry is tilted by the tilt driving unit. A medical image photographing apparatus comprising a moving means for moving the position of the top plate.

Claims

A gantry with an opening to be a shooting space,
A tilt driving unit for tilting the gantry to a predetermined tilt angle;
A projector that is fixed to the gantry and irradiates a guide light for positioning at a position away from a photographing position by a predetermined reference distance;
A medical imaging apparatus comprising: a top plate for placing a subject ; and a bed for transporting the top plate to a predetermined position in an opening provided in the gantry,
Moving means for moving the position of the top plate of the bed so that the target site reaches the imaging position after the target site is positioned using the projector while the gantry is tilted by the tilt drive unit A medical image photographing apparatus comprising:

A tilt angle detecting means for detecting a tilt angle of the gantry;
When the guide light emitted by the projector illuminates at least a direction parallel to the rotation axis of the gantry and a direction parallel to the imaging section,
The moving means moves the top plate in a horizontal direction and a vertical direction by a moving amount corresponding to the tilt angle detected by the tilt angle detecting means, thereby causing the target site to reach the imaging position. The medical image photographing device according to claim 1.

A tilt angle detecting means for detecting a tilt angle of the gantry;
When the guide light emitted by the projector illuminates a direction parallel to the imaging section and does not irradiate a direction parallel to the rotation axis of the gantry,
The moving means moves the top board in the horizontal direction by the reference distance, and further moves the top board in the horizontal direction or the vertical direction by a correction amount corresponding to the tilt angle detected by the tilt angle detection means. The medical image photographing apparatus according to claim 1, wherein the target part is made to reach the photographing position by correcting to either one.
