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 data processing apparatus (10) includes: an input portion (13, 14) configured to receive IOS data and CT data as an input, the IOS data being obtained by performing scanning by an intra oral scanner (20) and including coordinate data of a point group indicating a surface shape of a tooth row including an IOS crown (21) and an IOS gingiva (22), the CT data being obtained by performing capturing by a CT imaging device (30) and including volume data of a CT crown; and processing circuitry (11). The processing circuitry (11) replaces, in the CT data, a crown part of a CT tooth included in the CT data with which a shape of the IOS crown (21) matches, with the IOS crown (21) included in the IOS data, and performs synthesis in such a way that the IOS gingiva (22) is arranged near the IOS crown (21) after replacement.

摘要： A first position setting unit receives an operation to designate a position in a mesiodistal on a panoramic tomographic image displayed on a display, and sets a first position on a curved section based on the designation operation. The fluoroscopic imaging information providing unit provides information irradiating a subject with an X-ray beam along a direction having a component of a tangential direction at the first position of the curved section to execute fluoroscopic imaging acquiring a fluoroscopic image to a main body. A second position setting unit receives an operation to designate a position in a buccolingual direction on the fluoroscopic image displayed on the display, and sets a second position in the buccolingual direction based on the designation operation. An imaging region setting unit sets an imaging region of CT imaging based on the second position.

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.

摘要： A panoramic X-ray imaging apparatus (20, 200) includes: an X-ray generating unit (42); an X-ray detecting unit (44); a support (40), for example, a turning arm, that supports the X-ray generating unit (42) and the X-ray detecting unit (44); a drive mechanism (60) that turns at least the X-ray generating unit (42) and the X-ray detecting unit (44) by driving the support (40); a displacement mechanism (82, 47), for example, a vertical drive unit, that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit (44); a subject holding unit (32) that holds an imaging subject; a turning controller (100, 202), for example, a imaging controller, that controls the turning by a drive mechanism and the displacement mechanism (82, 47). The turning controller (100, 202) controls the drive mechanism and the displacement mechanism (82, 47) so as to add the movement avoiding the contact with the shoulder (S) of the imaging subject during the turning of the X-ray generating unit (42) and the X-ray detecting unit (44) by the drive mechanism during the panoramic X-ray imaging.
