Abstract: The invention relates to a medical X-ray imaging apparatus having a frame part, an X-ray source for producing X-rays, a radiation receiver for detecting radiation transmitted through an object, and a support for supporting the X-ray source and the receiver in positions on opposite sides of the object. The support is connected to the frame part so as to rotate around the axis of rotation provided with actuator means for rotating the support around the said axis of rotation. The apparatus makes possible both panoramic imaging and CT imaging, as selected by the operator. The X-ray apparatus is configured to adjust the ratio of enlargement so as to be optimal for each method of imaging used respectively.

Abstract: An x-ray apparatus for intraoral imaging applications includes a linkage mounted on a support structure, to which is connected an x-ray source for generating x-radiation and directing same to a receiver instrument placed in a patient's mouth. The linkage includes a first arm member, articulated to the support structure and adapted to be pivotable about a substantially vertical axis, a second arm member, connected to the end of the first arm member spaced from the support structure and adapted to be pivotable around a substantially vertical axis and a horizontal axis, and a third arm member, connected to the opposite end of the second arm member and adapted to be pivotable around a substantially horizontal axis, the unsupported end of the latter having the x-ray source mounted thereon with an articulated joint, which allows pivoting of the x-ray source to various positions.

Abstract: A method and an apparatus for panoramic dental X-raying comprises an arm (7) rotating about an axis (6), a radiation source (9) at one end (8) of the arm for generating an X-ray beam (12), a shutter (13) for shaping the X-ray beam, and at the opposite end (10) of the arm, a recorder (11) for receiving the X-ray beam after it has passed through the dental arch for forming an image of the dental arch. The X-raying is performed with rotation of the arm (7) so as to image substantially the entire length of the dental arch. The shutter (13) narrows the X-ray beam (12) in the front area of the dental arch in order to increase the thickness of the sharply imaged layer compared to the two sides of the dental arch.

The X-raying is performed with rotation of the arm (7) so as to image substantially the entire length of the dental arch. According to the invention, the shutter (13) narrows the X-ray beam (12) in the front area of the dental arch in order to increase the thickness of the sharply imaged layer compared to the two sides of the dental arch. This solution allows compensation for the decrease in the width of the sharp layer caused by the orthogonal X-raying and for the consequently shortened X-raying radius in the front area of the dental arch.
