X-ray computed tomography apparatus

摘要

In one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, an X-ray detector, a rotating mechanism, a high voltage generating unit, a reconstruction processing unit, a projection image generating unit configured to generate a projection image based on output from the X-ray detector, an image display unit, and a fluoroscopy control unit configured to control the rotating mechanism, the high voltage generating unit, the X-ray detector, the projection image generating unit and the image display unit to implement stereo fluoroscopy.

1. An X-ray computed tomography apparatus, comprising:
a single X-ray tube; an X-ray detector including a plurality of X-ray detection elements arrayed two-dimensionally; a rotating mechanism that supports the single X-ray tube and the X-ray detector so as to allow the single X-ray tube and the X-ray detector to rotate around an object; a high voltage generator that generates a high voltage to be applied to the single X-ray tube so as to make the single X-ray tube generate X-rays; a reconstruction processor that reconstructs multislice tomographic data or volume data based on an output from the X-ray detector; a setting supporter that sets respective angles of a pair of viewpoints on a rotational orbit of the single X-ray tube which corresponds to a binocular parallax; a projection image generator that generates a series of right-eye projection images corresponding to one of the pair of viewpoints and a series of left-eye projection images corresponding to the other of the pair of viewpoints based on an output from the X-ray detector during rotation of the single X-ray tube, an image display; and a fluoroscopy controller that controls the rotating mechanism, the high voltage generator, the X-ray detector, the projection image generator, and the image display to implement stereo fluoroscopy using the series of right-eye projection images and the series of left-eye projection images as a moving image on the image display in real time during rotation of the single X-ray tube, wherein the object is automatically irradiated with X-rays every time the single X-ray tube passes through the set angles set by the setting supporter.
