摘要： 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.

摘要： 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.

摘要： An X-ray imaging apparatus including an X-ray tube which emits X-rays, an image sensor which detects X-rays which pass through an object, a support arm which supports the X-ray tube and the image sensor so that they are opposed to each other across the object, a driving motor which moves the support arm in a predetermined direction, a gain adjustment circuit which adjusts the imaging sensitivity of the image sensor and a controlling circuit for controlling the gain of the adjusting circuit. The controlling circuit controls the gain adjusting circuit on the basis of the detected image density of the image sensor. When the adjustment by means of the gain adjusting circuit is insufficient, the controlling circuit controls X-ray tube current, X-ray tube voltage and driving speed adjusters.
