    • An X-ray photography apparatus including: a turning arm that supports an X-ray generator and an X-ray detector while the X-ray generator and the X-ray detector are opposed to each other so that a head of a patient can be interposed therebetween; and a moving mechanism that turns the turning arm about a turning axis with respect to the head and moves the turning arm in a direction perpendicular to the turning axis with respect to the head. The X-ray photography apparatus further includes: an image processor that generates an X-ray image based on an electric signal output from the X-ray detector; and a photographic region designation receiving part that designates part of a row of teeth along a dental arch as a pseudo intraoral radiography region. The image processor generates plural tomographic images by applying convolution and filtered back projection to X-ray image data obtained by pseudo intraoral radiography.

    • The invention relates to a medical x-ray imaging apparatus including a support structure (1) which supports a substantially ring-shaped structure, an O-arm (2) supporting imaging means (21, 22), to which O-arm (2) is arranged an examination opening (4). The ring-shaped structure (2) supporting the imaging means is arranged movable with respect to said support construction (1) at least in vertical direction. A patient stool (30) is arranged to be positioned in connection with the apparatus, as well as positioning means (32, 33, 34) in connection with said examination opening (4) for positioning the patient stool (30) in the examination opening (4).

    • The mammographic apparatus of this invention maintains peripheral portions of the breast area Ma of the sternal plate of a patient M in contact with a sternal plate contact box 3 during radiography for RI distribution images of the breast area Ma of the patient M. Since the body motion accompanying respiration of the patient M shifts from the breast side to the back side, the motion of the breast area Ma of the patient M accompanying respiration of the patient M is suppressed easily. In addition, since radiography for RI distribution images is carried out with the patient M in a seated position seated on a seating unit 2, the apparatus is compact and can installed in a limited area, compared with an apparatus that carries out radiography for RI distribution images with a patient in a sleeping position lying on her back or on a side on a top board.
    • 本发明的乳房X线摄影装置在患者M的乳房区域Ma的RI分布图像的放射线照相期间保持患者M的胸骨板的胸部区域Ma的周边部分与胸骨板接触盒3接触。由于身体 伴随着患者M的呼吸的运动从乳房侧向背侧移动,患者M的乳房区域Ma的运动伴随着患者M的呼吸被容易地抑制。 此外,由于RI分布图像的放射线照相是在患者M位于座位单元2上的就座位置中进行的,所以与进行RI分布放射线照相术的装置相比,该装置是紧凑的并且可以安装在有限的区域中 患者躺在躺在她背后或顶板上的一侧的患者的图像。

    • The invention relates to a medical x-ray imaging apparatus which is specifically designed for enabling three-dimensional imaging of relatively small volumes from the area of extremities of a patient. The apparatus includes a support construction (1) supporting a substantially ring-shaped structure (2), an O-arm (2), which in turn supports imaging means (21, 22) and which O-arm (2) is arranged with an examination opening (4). The imaging means (21, 22) are arranged movable within the O-arm (2). A positioning support (8) is arranged in connection with said examination opening (4) whose location with respect to the O-arm (2) is arranged adjustable. Preferably the apparatus comprises a control system comprising a control function for moving the positioning support (8) in a first direction at a first speed within the area of the examination opening (4) and for simultaneously moving the O-arm (2) with respect to its support construction (1) substantially at said first speed in substantially opposite direction than said first direction.
