摘要： A planigraphic X-ray apparatus comprising a rotation mechanism for rotating a support member which supports an X-ray generator and an X-ray detection surface to rotate the X-ray generator and the X-ray detection surface around a subject, a position adjustment mechanism for setting the position of the rotation center of the support member rotated by the rotation mechanism and a linear movement means for moving the support member in the direction approximately perpendicular to the direction of the X-ray irradiated from the X-ray generator, whereby the X-ray detection surface is driven in the direction opposite to the movement of the linear movement means and the X-ray generator is rotated toward the X-ray detection surface in synchronization with the movement of the linear movement means. The position adjustment mechanism and the rotation mechanism are used only to set the position and direction of the support member with respect to the subject, and planigraphic photographing is possible only by moving the support member using a linear movement means exclusively provided for the support member, thereby facilitating the positioning operation of the support member with respect to a given planigraphic plane, simplifying the control program and making the entire apparatus compact and inexpensive.

摘要： A rotational tomographic X-ray apparatus is disclosed as having an X-ray detection surface disposed parallel to a planigraphic plane selected as a subject to be photographed, and comprising a mechanism for linearly moving the X-ray generator and the X-ray detection surface of the apparatus in relatively opposite directions parallel to the planigraphic plane with the head of a patient positioned therebetween, and for controlling the irradiation direction of X-rays so that the irradiated X-rays always pass the same specific region in the planigraphic plane and are incident on the X-ray detection surface in synchronization with the linear movement. With this apparatus, clear planigraphic photographing with no distortion is possible and the magnifying ratios of X-ray images can be changed easily.

摘要： An automatic exposure control method for an image produced on a solid-state image sensing device in which intensity of radiation light irradiated to an object to be examined from a radiation source is feedback controlled. The solid-state image sensing device comprises a picture element producing part where electric charges generated by way of photo-electric conversion when receiving exposure, and a dark current measuring part where a dark current is generated and stored without receiving exposure. The image is produced while performing radiography in a manner that the intensity of radiation light is feedback controlled so as to keep, within a predetermined density range, the amount value which is defined by removing the charge signals stored on a specified pixel element or a specified pixel element column in the dark current measuring part of the image sensing device from the charge signals stored on a specified pixel element or a specified pixel element column in the picture element producing part of the image sensing device.

摘要： An X-ray device for generating a panoramic tomogram is designed so that a revolving arm can move between a first position, where an X-ray generator and an X-ray receiver that are both supported by the revolving arm oppose each other through the head of a patient positioned in a patient positioning station, and a second position, where an operator of the X-ray device can look at the patient's head from a side view, thereby allowing the operator to properly position the patient in the patient positioning station. The incorporation of a second X-ray receiver additionally allows for the generation of a cephalogram. The incorporation of a blind prevents the patient from visually or physically interacting with selected components of the apparatus.
