Abstract
【解決手段】X線管装置は、アノード4の後端よりも更に外側には配置した電磁石7に通電すると瞬時にアノード4の後端を吸着する機構を備える。これにより左右のアノード4,4は軸方向外方に移動する。その結果2つのX線発生源間の距離が瞬時に拡大したことになる。
【選択図】図2
Description
また、2つのアノード間の距離を可変とすることについては何ら開示されていない。
アノード4は電子線が当たる先端が傾斜面とされ、後端は管1に形成した開口から外側に突出し、この後端と開口との間にベローズ5を設け、管1内の真空状態を維持するとともにアノード4を軸方向に移動可能としている。アノード4の先端面は前記したX線発生源S1、S2に相当する。
前記カソード2と中間電極6との間に電圧を印加することでカソード2から電子が発生する。更に中間電極6と前記アノード4との間に電圧を印加することで、発生した電子が接地電極アパーチャーで収束し、加速してターゲットであるアノード4に衝突してX線が発生する。
即ち、アノード4の先端には傾斜角度は同じであるが、軸方向の位置がことなる第1の傾斜面4aと第2の傾斜面4bが位相をずらせて形成されている。そしてアノード4を軸廻りに180°回転させることで第1の傾斜面4aと第2の傾斜面4bとを入れ替えることでX線発生源間の距離D3が変化する。
前記カソード2と中間電極6との間に電圧を印加することでカソード2から電子が放出される。更に中間電極6と前記アノード4との間に電圧を印加することで、放出した電子が接地電極アパーチャーで収束し、加速してターゲットであるアノード4に衝突してX線が発生する。
Claims (3)
- エミッタとして機能する1つのカソードとターゲットとして機能する2つのアノードが1つの管内に配置され、前記カソードは容器の中心部に1つ配置され、前記アノードは容器の両端部に配置されていることを特徴とするステレオX線発生装置。
- 請求項1に記載のステレオX線発生装置において、前記容器の両端部に配置されたアノードは容器の軸線に沿って互いに接近・離反可能とされることを特徴とするステレオX線発生装置。
- 請求項2に記載のステレオX線発生装置において、前記アノードの軸線に沿った接近・離反は電磁石への通電、ソレノイドへの通電またはアノードの回転によることを特徴とするX線発生装置。
