Abstract
An X-ray apparatus capable of performing both computerized tomography (CT) imaging and usual radiography imaging (usual imaging) can realize high definition even in the usual imaging. In the X-ray apparatus, for the usual imaging, since a chair serving as a supporting structure for supporting a subject on a rotatable table is not required, the chair is withdrawn from an imaging field. The usual imaging is controlled so as to be permitted when the supporting structure is withdrawn from the imaging field. For imaging a knee, for example, sliding the chair allows imaging keeping the knee being in the rotation center. Therefore, a wide variety of imaging operations can be realized with a single flat-panel sensor.
Claims24
An X-ray apparatus capable of operating in a first imaging mode of performing X-ray imaging while a subject is rotated and a second imaging mode of performing X-ray imaging while the subject remains stationary, the X-ray apparatus comprising:
- a rotatable table for rotating the subject;
- a securing member for securing the subject, the securing member being disposed on the rotatable table;
- a moving unit configured to move the securing member between a position within an imaging field of the X-ray apparatus and a position outside the imaging field;
- a detecting unit configured to detect a position of the securing member;
- and
- a controlling unit configured to inhibit the apparatus from operating in the second imaging mode while the position of the securing member is detected to be present within the imaging field of the X-ray apparatus.
An X-ray apparatus capable of operating in a first imaging mode of performing X-ray imaging while a subject is rotated and a second imaging mode of performing X-ray imaging while the subject remains stationary, the X-ray apparatus comprising:
- a rotatable table for rotating the subject;
- a rotation locking unit configured to lock the rotatable table so as to inhibit rotation of the rotatable table;
- a detecting unit configured to detect whether the rotation locking unit has locked the rotatable table so as to inhibit the rotatable table from being rotated;
- and
- a controlling unit configured to inhibit the apparatus from operating in the first imaging mode while the detecting unit detects that the rotatable table is locked so as not to be rotated.
