摘要： An object of the present invention is to prevent an X-ray generator and an X-ray detector that turn around a subject from contacting with the subject. An X-ray CT imaging apparatus includes a turning support, a turning drive mechanism, a subject physique setting unit, and a turning controller. The turning support supports the X-ray generator and the X-ray detector such that the X-ray generator and the X-ray detector are opposed to each other with the subject sandwiched therebetween. The turning drive mechanism includes a turning mechanism that turns the turning support about a mechanical turning axis and a turning axis moving mechanism that moves the mechanical turning axis. Position control of the turning axis X1 is performed according to a size of a physique set by the subject physique setting unit.

摘要： An X-ray generation unit includes an X-ray generation source and an X-ray beam forming unit, and irradiates a head with an X-ray beam. An X-ray detection unit includes an X-ray detector that receives and detects the X-ray beam transmitted through the head. The support supports the X-ray generation unit and the X-ray detection unit. A drive mechanism moves the support such that the X-ray generation unit and the X-ray detection unit turn about an axis extending in a direction parallel to an apparatus vertical direction and around the head. An X-ray generation source moving unit moves the X-ray generation source in the apparatus vertical direction. The X-ray imaging apparatus increases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus upper side, and decreases a spread in the apparatus vertical direction of the X-ray beam when the X-ray generation source is located on an apparatus lower side.

摘要： A medical X-ray CT imaging apparatus includes an X-ray generator that generates a cone beam, an X-ray detector, a support that supports the X-ray generator and the X-ray detector while the X-ray generator and the X-ray detector are opposed to each other, a turning drive unit that turns the X-ray generator and the X-ray detector, which are supported by the support, an imaging information receiving unit, and an X-ray output condition setting unit. The imaging information receiving unit receives an imaging area setting relating to at least one of a size of an imaging area, an imaging purpose, and an imaging region. The X-ray output condition setting unit automatically sets an output condition of the X-ray generator according to at least one of the size of the imaging area, the imaging purpose, and the imaging region, which are received by the imaging information receiving unit.

摘要： When X-ray CT imaging is performed with a part located close to a front of a head as the imaging region, using the turning mechanism and the distance changing mechanism, the turning controller causes the X-ray generator and the X-ray detector to turn around the head while locating the imaging region therebetween, and causes the X-ray detector to turn along a go-around orbit, in which the X-ray detector comes close to the imaging region with respect to a front side of the head and moves away from the imaging region with respect to a rear side, by changing a distance between the X-ray detector and the center of the imaging region.

摘要： An X-ray imaging apparatus receives mode selection using a mode selection receiving unit including a mode setting unit and an operation display. When a CT mode is selected by the mode selection receiving unit, an X-ray beam shape adjuster shapes an X-ray beam into an X-ray cone beam in which a center beam that is a center of the X-ray beam is orthogonally incident on a body axis of a head. When a panoramic mode is selected, the X-ray beam shape adjuster shapes the X-ray beam into an X-ray narrow beam in which the center beam is incident on the body axis from obliquely below to obliquely above, the X-ray narrow beam having a length in a direction of the body axis.

摘要： An X-ray generator 11 generating an X-ray cone beam BX11 and a two-dimensional X-ray detector 21 detecting the X-ray cone beam BX1 are supported by a support arm 30 while facing each other, and the X-ray generator 11 and the two-dimensional X-ray detector 21 are turned with an object M1 interposed therebetween. An energy conversion unit 23 is disposed between the two-dimensional X-ray detector 21 and the object M1. Filters 231 and 233 having X-ray beam energy distribution conversion characteristics different from each other are arrayed in the energy conversion unit 23. In X-ray photography, an energy conversion unit moving mechanism 25 is moved in a direction along a detection surface 21S of the two-dimensional X-ray detector 21 such that the energy conversion unit 23 traverses the X-ray cone beam BX11 in turning the support arm 30.
