A display device for a medical X-ray photography apparatus may include: a display panel including a photography mode selection region where a plurality of photography mode selection images corresponding to a plurality of X-ray photography modes are displayed; an interface that receives a selection operation to select one of the photography mode selection images displayed on the display panel; a processor that performs display processing of the selected photography mode selection image displayed on the display panel in response to the selection operation received through the interface; and an illustration display region included in the display panel where an illustration corresponding to the selected photography mode selection image is displayed. When the selection operation is received, the selected photography mode selection image is displayed in a visually distinguishable manner, and the illustration corresponding to the selected photography mode is displayed in the illustration display region.

The present invention has an object of providing an X-ray CT imaging device which can direct X-ray to an area of interest appropriately even when, for example, the height of the area of interest with respect to the X-ray detector, which is revolving, varies with respect to the revolution direction, and thus can reduce the amount of unnecessary exposure to the X-ray and can perform X-ray imaging of the area of interest with certainty. In an X-ray CT imaging device for performing X-ray CT imaging of a CT imaging area of a subject, during the X-ray CT imaging when a revolving arm is revolving, the expansion in a length direction of an X-ray cone beam, which is to be restricted by length direction blocking plates, is adapted to the shape of the CT imaging area in accordance with the revolution position of the revolving arm.

X-ray CT imaging device

An X-ray CT apparatus including an X-ray generator, an X-ray detector, a support part, and a base that rotatably supports the support part. The support part includes an exterior part made of carbon fiber reinforced plastic, and the X-ray generator and the X-ray detector are supported by the exterior part while being opposed to each other. The base rotatably supports the support part such that the X-ray generator and the X-ray detector turn about a turning axis.

X-ray CT apparatus

A phosphor, an optical fiber plate containing lead particles, a CCD, and an X-ray shielding member consisting of copper tungsten are sequentially stacked on a substrate from an X-ray incident surface side and sealed in a container made of a light-shielding synthetic resin. The substrate has projecting portions projecting toward the direction of X-ray incident along three sides of the X-ray incident surface. Each of these projecting portions has an overhang portion projecting toward the optical fiber plate. The overhang portions are close to or in contact with corresponding side surfaces of the optical fiber plate so that the optical fiber plate is fixed at a predetermined position. The container has, in the inner surface, convex portions corresponding to the projecting portions, so the substrate is fixed in the container. The output signal from the CCD is sent to an external display unit via a cable extracted from the convex portion of the container through an FPC connector and an FPC provided on a surface opposite to the incident surface.

X-ray image pickup apparatus for intraoral radiography

An X-ray detecting element detects an image produced by X-ray irradiation. An apparatus case capable of being inserted into a mouth has an X-ray irradiation face having different dimensions in two directions perpendicular to each other, and houses the X-ray detecting element. A cable is connected to the apparatus case to transmit a signal from the X-ray detecting element to the outside of the apparatus case. The cable is drawn out from the apparatus case in a direction which is parallel with the X-ray irradiation face and perpendicular to the longitudinal direction of the X-ray irradiation face. According to this configuration, the cable does not obstruct the imaging operation in a course of imaging teeth in a mouth, particularly a molar portion. Therefore, an imaging operation can be easily conducted without giving the subject an unpleasant feeling.
