| description | To control the quality of an irradiated X-ray easily and arbitrarily.SOLUTION: An X-ray CT apparatus includes a negative pole, a positive pole, a first thermal electron adjusting part, a second thermal electron adjusting part, and a control part. The negative pole generates a thermal electron. The positive pole receives the thermal electron irradiated from the negative pole and generates an X-ray. The first thermal electron adjusting part adjusts the track of the thermal electron. The second thermal electron adjusting part further adjusts the track of the thermal electron adjusted by the first thermal electron adjusting part. The control part controls an irradiation angle of the thermal electron to the positive pole while keeping a focal position of the thermal electron in the positive pole constant by controlling the first thermal electron adjusting part and the second thermal electron adjusting part.SELECTED DRAWING: Figure 2A
【課題】照射されるＸ線の線質を容易かつ任意に制御可能とすること。【解決手段】実施形態に係るＸ線ＣＴ装置は、陰極と、陽極と、第１の熱電子調整部と、第２の熱電子調整部と、制御部とを備える。陰極は、熱電子を発生する。陽極は、前記陰極から照射される熱電子を受けて、Ｘ線を発生する。第１の熱電子調整部は、前記熱電子の軌道を調整する。第２の熱電子調整部は、前記第１の熱電子調整部により調整された熱電子の軌道を更に調整する。制御部は、前記第１の熱電子調整部と、前記第２の熱電子調整部とを制御することにより、前記陽極における前記熱電子の焦点位置を一定に保持しつつ、前記陽極への熱電子の照射角を制御する。【選択図】図２Ａ |
