The present invention provides a technology for acquiring an X-ray tomographic image of high resolution while suppressing increase in X-ray exposure. A radiation dose setting unit 308 generates radiation dose control data used to alter a unit-time radiation dose of an X-ray beam BX1 with which a subject M1 is irradiated during X-ray tomography. An imaging control unit 80 performs control, on the basis of said radiation dose control data, so that the X-ray intensity I1 is made relatively lesser at the time when central axis X-ray CBX1 (irradiation axis) of an X-ray beam BX1 emitted from an X-ray generator 42 is not orthogonally oriented to a tomographic layer of interest LOI as compared to the X-ray intensity I0 at the time when the central axis X-ray CBX1 is oriented orthogonal to said tomographic layer LOI.
Provided is a technique for acquiring a high-resolution X-ray projection image without interfering with rotation of an X-ray generator and an X-ray detector. X-ray beams BX1 are radiated through an imaging region ROI from a plurality of directions to obtain an X-ray projection image, by causing an X-ray generator 42 and an X-ray detector 52 to rotate around the head of a subject M1. When a central axis X-ray beam CBX1 which passes through a central axis of rotation RA1, from among the plurality of X-ray beams BX1, is orthogonal to a layer of interest LOI, the X-ray detector 52 is brought closer to the layer of interest LOI and the X-ray generator 42 is moved further away from the layer of interest LOI than when the central axis X-ray beam CBX1 is not orthogonal to the layer of interest LOI.

There is provided a new X-ray imaging apparatus by the use of which X-ray CT and panoramic imaging can be effectively performed. In an X-ray imaging apparatus which rotates an X-ray generating section and an X-ray detecting section around an imaging object arranged between these X-ray generating section and the X-ray detecting section and also detects in the X-ray detecting section X-rays having been radiated from the X-ray generating section and transmitted through the imaging object to form an X-ray image, a panoramic imaging mode in which the X-ray generating section and the X-ray detecting section are driven to form a panoramic image of the imaging object and an offset scan/CT mode in which the X-ray generating section and the X-ray detecting section are driven to form a tomographic image of the imaging object are set, so as to selectively execute these two imaging modes. Consequently, the panoramic imaging mode and the offset scan/CT mode can be arbitrarily selected, thereby allowing formation of an X-ray imaged image that is optimum for treatment.

MEDICAL DIGITAL X-RAY IMAGER AND MEDICAL DIGITAL X-RAY SENSOR
A medical digital X-ray imager having imaging modes. Support means supports an X-ray source and a digital X-ray sensor having a two-dimensional detecting surface for detecting X-rays opposed to the X-ray source, with an object interposed between them. Image restructurizing means collects data from the digital X-ray sensor and restructures an image from the collected data. The operator selects either a first imaging mode or a second imaging mode. In the second imaging mode, the X-ray application field is different from that of the first imaging mode, and the image data read area of the digital X-ray sensor is smaller than that of the digital X-ray sensor operating in the first imaging mode.
The present invention provides a maintenance apparatus for increasing the service life of a medical handpiece. The maintenance apparatus is provided with a first fluid supply which feeds a maintenance fluid to the bearings of a handpiece, capable of rotatably supporting a rotary tool, and a second fluid supply which feeds the maintenance fluid to the chucking structure of the handpiece, capable of detachably holding the rotary tool.
