Abstract
An X-ray imaging apparatus includes an imaging unit which is rotatable relative to a platform about a shaft portion perpendicular to an X-ray detecting surface, so as to change the orientation relative to a subject.
Claims17
An X-ray imaging apparatus, comprising:
- a support member for rotatably supporting an X-ray detector for detecting X-ray radiation to obtain an X-ray image;
- a selector for selecting an imaging mode of the X-ray imaging apparatus;
- and
- a warning transmitter for transmitting a warning in a case that the X-ray detector is not supported in a manner corresponding to the selected imaging mode.
1 more element
A C-arm X-ray imaging device, comprising:
- an X-ray detector defining a rectangular detection area and configured to be movable between at least a first orientation and a second orientation;
- an X-ray generator;
- a selection unit configured to select an imaging mode;
- an orientation detector configured to detect an orientation of the X-ray detector in response to the selection by the selection unit;
- a control unit configured to selectively operate the C-arm X-ray imaging device in either a computed tomographic imaging mode or a still imaging mode;
- a driving unit configured to relatively rotate the X-ray generator and the X-ray detector around a subject when the C-arm X-ray imaging device operates in the computed tomography imaging mode;
- a warning unit configured to output a warning when imaging is initiated, wherein the warning unit outputs a warning except when either of the sides of the rectangular detection area is substantially parallel to a longitudinal axis of the subject;
- and
- a receiving unit configured to receive information input by a user indicating whether or not imaging operation is permitted when the X-ray detector is oriented in neither the first orientation nor the second orientation,
- wherein the control unit permits operation of the X-ray imaging apparatus in the selected imaging mode in response to the input of information indicating that imaging operation is permitted when the X-ray detector is oriented in neither the first orientation nor the second orientation.
7 more elements
A method of operating an X-ray imaging apparatus for detecting X-ray radiation to obtain an X-ray image, the X-ray imaging apparatus including a support member for movably supporting an X-ray detector in at least one of a plurality of imaging modes of the X-ray imaging apparatus, the method comprising:
- detecting an orientation of the X-ray detector;
- selecting an imaging mode of the X-ray imaging apparatus;
- determining whether the detected orientation corresponds to the selected imaging mode;
- and
- outputting a warning in a case that the detected orientation is determined as not corresponding to the selected imaging mode.
