Abstract: According to an X-ray imaging device for performing CT imaging, a main body control section controls at least one of an X-ray revolution plane formed by an X-ray cone beam along with the revolution of a revolving arm and a revolution range of the revolving arm in accordance with a CT imaging area accepted by an imaging area setting screen. Such control is performed in order to decrease X-ray radiation to a high sensitivity site in the area that revolves during the CT imaging, the high sensitivity site being positionally set in a biological body as a site that is sensitive to X-rays.

Abstract: A air-driven cutting device for medical treatment (a handpiece (10)) comprises a housing (18) for a head portion (14). The housing (18) accommodates a rotary cylinder (60) for holding a cylindrical cutting tool (46) inserted through the tool inlet (42) of the housing, and a turbine blade (62) mounted around and secured on the rotary cylinder. With this arrangement, a compressed air is blown onto the turbine blade to rotate the turbine blade, the rotor and the cutting tool. Particularly, a part or a whole of the end portion of the rotary cylinder in the vicinity of the tool inlet is covered with the cover section (42) of the housing. Therefore, the rotary cylinder does not contact the teeth or the tissues of the buccal cavity.

Abstract: A scan type digital X-ray imaging apparatus comprising an X-ray generator for emitting X-ray slit beams, an X-ray detector for detecting X-ray transmitted through an object to be examined, and an object fixing means disposed between the X-ray generator and the X-ray detector, for holding the object in an appropriate position for X-ray photography, in which X-ray beam scanning is performed in a manner that the X-ray slit beam is emitted from the X-ray generator for the object while the X-ray generator and the X-ray detector are synchronously moved in the same direction with the object interposed therebetween, thereby producing an X-ray image of the object. In the X-ray imaging apparatus, the scanning speed of the X-ray slit beam is controlled depending on the X-ray transmitted amount through the object to be examined detected by the X-ray detector during the X-ray beam scanning is performed, whereby soft and hard tissues appearing in the X-ray image are amended in each contrast and/or in each density.
