摘要： 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.

摘要： A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit; a support that supports the X-ray generating unit and the X-ray detecting unit; a drive mechanism that turns at least the X-ray generating unit and the X-ray detecting unit by driving the support; a displacement mechanism that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit; a subject holding unit that holds an imaging subject; a turning controller that controls the turning by a drive mechanism and the displacement mechanism. The turning controller controls the drive mechanism and the displacement mechanism so as to add the movement avoiding the contact with the shoulder of the imaging subject during the turning of the X-ray generating unit and the X-ray detecting unit by the drive mechanism during the panoramic X-ray imaging.

摘要： 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.

摘要： An X-ray CT photographic apparatus including: a beam shaping mechanism that regulates an irradiation range of an X-ray generated from an X-ray generator and shapes the X-ray into an X-ray cone beam; and a main body controller that changes a read region, where an X-ray detection signal is read in the X-ray detector, according to the irradiation range of the X-ray cone beam. The main body controller changes the irradiation range of the X-ray cone beam to an x-axis direction during an X-ray CT photography such that only a set CT photographic region is irradiated with the X-ray cone beam according to the set CT photographic region input through a CT photographic region setting unit. The main body controller changes a read region in an X-ray detector with respect to the x-axis direction in a detection surface of the X-ray detector during the X-ray CT photography.

摘要： 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.

摘要： 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.
