Abstract: Disclosed is a dental X-ray imaging apparatus having a radiographing housing so as to provide a stable radiographing environment to an examinee. The dental X-ray radiographing apparatus includes a radiographing unit including a rotary arm, an X-ray generator, and an X-ray sensor, and a radiographing housing for covering an upper part, an outside and an inside of an operating range of the radiographing unit. The imaging apparatus further includes a lifter configured to move the radiographing housing, and a handle frame disposed at a lower part of the radiographing housing with a variable height and including a chin rest, wherein the lifter moves the radiographing housing such that the distance between the chin rest and the radiographing housing is constant.

Abstract: An X-ray imaging device and an X-ray imaging method for obtaining 3D X-ray images of an entire field of view (FOV). The device includes an X-ray source for radiating X-rays to a part of an FOV and an X-ray sensor for detecting the X-rays, which have passed through the part of the FOV. The X-ray sensor has a width narrower than the radius of a smallest circle including a cross section perpendicular to the longitudinal direction of the FOV. A rotating arm supports the X-ray source and the X-ray sensor to face each other with the FOV therebetween. The rotating arm rotates and moves about an axis of rotation between the X-ray source and the X-ray sensor so that the X-rays are radiated to the entire area of the FOV in various directions of the FOV.

Abstract: The present invention relates to an X-ray imaging apparatus which obtains an X-ray image of a subject placed between a generator and a detector by means of the rotation of the generator and the detector. The X-ray imaging apparatus comprises: the generator and the detector, which are disposed to face each other while having an object to be imaged therebetween, for irradiating and detecting an X-ray; a rotation drive unit for rotating the generator and the detector while having the object to be imaged therebetween; and a bed in which a first portion for supporting the object to be imaged is disposed between the generator and the detector. When the height of at least one from among the generator and the detector is T1, the height of the other is T2, and the height of the first portion is T3, said T1, T2, and T3 are T1>T3>T2.
