摘要： In an apparatus without a helical movement, a reconstruction error considerably increases as a radiation angle increases. In a prior art embodiment, for example, a one-side value of the radiation angle is 9.5 degrees, and it is predicted that the reconstruction error at its periphery considerably increases. In a radiation imaging apparatus including a radiation generating source for radiating radiation to a subject, a rotating unit for rotating the subject exposed to the radiation from the radiation generating source, and a two-dimensional detector for detecting radiation, a distance between the radiation generating source and the two-dimensional detector is approximately set to a value equal to or more than 240 cm.

摘要： A slit radiography apparatus is provided with an absorption device comprising electrically controllable piezoelectric tongues. Upper and/or lower deflections of the tongues are limited to a maximum by trips outside the X-ray fan beam. More than one strip can be present as seen in the length direction from the fixed ends of the tongues Thus deflections of the tongues are limited and great phase changes in the control signals without resultant oscillations can take place during the time the tongue are restricted in their movement by the strip.

摘要： A machine for examining the interior of a patient which includes a movable support for the patient, a frame having an opening adapted to circumscribe the patient, a shutter assembly, an X-ray beam source mounted on one side of the opening with a detector unit mounted on the opposite side of the opening such that a beam emitted by the source passes through the patient prior to reception by the detector. The machine includes mechanisms for rotating the framework about the patient while there is a relative translational movement of the X-ray source and receptor relative thereto. The apparatus also includes mechanism for tilting the framework such that other-than-vertical planes may be examined. The opening of the machine is sufficiently large to receive a human body and eliminates the requirement of water bags and other such paraphernalia commonly associated with equipment of this type.

摘要： The present disclosure relates to an x-ray imaging method using a variable imaging plane projection and to an x-ray imaging device applying the same. By applying a variable imaging plane projection using at least two sets of scan data for different heights obtained while varying the height of the x-ray generator from an imaging object, it is possible to solve problems caused due to a magnification effect generated in the x-ray imaging field based on a fan-beam-type or cone-beam-type x-ray generator, thereby providing more accurate x-ray image information.
