Abstract: An X-ray imaging apparatus receives mode selection using a mode selection receiving unit including a mode setting unit and an operation display. When a CT mode is selected by the mode selection receiving unit, an X-ray beam shape adjuster shapes an X-ray beam into an X-ray cone beam in which a center beam that is a center of the X-ray beam is orthogonally incident on a body axis of a head. When a panoramic mode is selected, the X-ray beam shape adjuster shapes the X-ray beam into an X-ray narrow beam in which the center beam is incident on the body axis from obliquely below to obliquely above, the X-ray narrow beam having a length in a direction of the body axis.

Abstract: An X-ray generator generating an X-ray cone beam and a two-dimensional X-ray detector detecting the X-ray cone beam are supported by a support arm while facing each other, and the X-ray generator and the two-dimensional X-ray detector are turned with an object interposed therebetween. A filter constitution body is disposed between the two-dimensional X-ray detector and the object. Filters having X-ray beam energy distribution conversion characteristics different from each other are arrayed in the filter constitution body. In X-ray photography, a filter constitution body moving mechanism is moved in a direction along a detection surface of the two-dimensional X-ray detector such that the filter constitution body traverses the X-ray cone beam in turning the support arm.

Abstract: The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); a driving state detecting unit (resistor for load detection, root canal length measuring circuit); and a controller. The hand piece drivably holds a cutting tool on a head unit. The power source drives the cutting tool. The driving unit drives the cutting tool with twist driving in which the normal rotation and the reverse rotation are repeated. The driving state detecting unit detects a driving state of the cutting tool. The controller changes at least one parameter of a rotation angle in the normal rotation, a rotation angle speed in the normal rotation, a rotation angle in the reverse rotation, and a rotation angle speed in the reverse rotation in accordance with the driving state of the cutting tool detected by the driving state detecting unit.
