前記撮像系の回転周期と前記照射範囲の変位周期との位相ずれを計測する位相ずれ量計測手段と、位相ずれ量計測手段の計測結果に基づいて、前記撮影系の回転周期と前記照射範囲の変位周期とを同期させる同期手段を備えたことを特徴とするＸ線装置。
[Claims]
[Claim 1]
In an X-ray apparatus that displaces the irradiation range of the X-ray beam according to the rotation of the photographing system and limits the irradiation of the X-ray beam to a part other than a predetermined part.
Based on the measurement results of the phase shift amount measuring means for measuring the phase shift between the rotation cycle of the imaging system and the displacement cycle of the irradiation range, and the rotation cycle of the imaging system and the irradiation range. An X-ray apparatus provided with a synchronization means for synchronizing with a displacement period.
（１）撮影系の回転に応じてＸ線ビームの照射範囲を変位させ、所定部位以外へのＸ線ビームの照射を制限するＸ線装置において、前記撮像系の回転周期と前記照射範囲の変位周期との位相ずれを計測する位相ずれ量計測手段と、位相ずれ量計測手段の計測結果に基づいて、前記撮影系の回転周期と前記照射範囲の変位周期とを同期させる同期手段を備えた。
(1) In an X-ray apparatus that displaces the X-ray beam irradiation range according to the rotation of the imaging system and limits the irradiation of the X-ray beam to a portion other than a predetermined portion, the rotation cycle of the imaging system and the displacement of the irradiation range. A phase shift amount measuring means for measuring the phase shift from the period and a synchronization means for synchronizing the rotation cycle of the photographing system and the displacement cycle of the irradiation range based on the measurement result of the phase shift amount measuring means are provided.
