X-RAY CT IMAGING DEVICE
To obtain as clear an X-ray CT image as possible by an X-ray generator's turning to a head as closely as possible, while suppressing contact of the X-ray generator and an X-ray detector turning around the subject with the head.SOLUTION: When performing X-ray CT imaging with one part near a fron...

| description | To obtain as clear an X-ray CT image as possible by an X-ray generator's turning to a head as closely as possible, while suppressing contact of the X-ray generator and an X-ray detector turning around the subject with the head.SOLUTION: When performing X-ray CT imaging with one part near a front of the head P as an imaging region R, an X-ray generator 22 and an X-ray detector 24 are turned and moved while positioning the imaging region R between them by a turning mechanism 32 and a distance change mechanism 34 and, by changing a distance of the X-ray detector 24 with respect to a center A of the imaging region R, the X-ray detector 24 is turned along an orbit Q that approaches the imaging region R with respect to a front side of the head P and leaves the imaging region R with respect to a rear side.SELECTED DRAWING: Figure 1
【課題】被写体周りを旋回するＸ線発生器及びＸ線検出器が頭部体に接触することを抑制しつつ、Ｘ線発生器がなるべく頭部に近くを旋回するようにすることで、なるべく鮮明なＸ線ＣＴ画像を得ることができるようにすることを目的とする。【解決手段】頭部Ｐの前寄りにある一部を撮影領域ＲとしてＸ線ＣＴ撮影する場合に、旋回機構３２と距離変更機構３４とにより、Ｘ線発生器２２とＸ線検出器２４とを、それらの間に撮影領域Ｒを位置させつつ旋回移動させると共に、撮影領域Ｒの中心Ａに対するＸ線検出器２４の距離を変更することで、Ｘ線検出器２４を、頭部Ｐの前側については撮影領域Ｒに近づき、後側については撮影領域Ｒから遠ざかる周回軌道Ｑに沿って旋回させる。【選択図】図１ |
