Abstract
A medical X-ray photographing apparatus includes: a support configured to hold the X-ray generator and the X-ray detector in a facing state, the X-ray generator emitting an X-ray, the X-ray detector outputting an electric signal according to an incident X-ray; a base body that rotatably holds the support; a turning driver that turns the support about a turning axis; and a turning controller that controls the turning driver. The medical X-ray photographing apparatus also includes: a light emitter disposed at a position on a virtual loop line surrounding the turning axis; and a light emitter controller that controls the light emitter in association with the turning of the support.
Claims21
A medical X-ray photographing apparatus comprising:
- a support configured to turn an X-ray generator and an X-ray detector about a predetermined turning axis while holding said X-ray generator and said X-ray detector such that said X-ray generator and said X-ray detector face each other, said X-ray generator configured to emit an X-ray, said X-ray detector configured to output an electric signal according to an incident X-ray;
- a support holder configured to rotatably support said support;
- a motor configured to turn said support held by said support holder;
- a turning controller configured to control said motor;
- an image processor configured to generate an X-ray image by processing a plurality of projection images based on said electric signal;
- a light emitter comprising a plurality of light emitting elements disposed on a virtual loop line surrounding said turning axis;
- and
- a processor configured to control said light emitter in association with turning of said support, wherein
- said processor controls said light emitter so that at least one of the plurality of light emitting elements acts in a way different from at least another one of the plurality of light emitting elements at least by lighting, turning off, blinking, or color, to indicate a movement of said support or a center of a swing angle of said support.
An X-ray photographing method in which X-ray photography is performed by emitting an X-ray from an X-ray generator toward an X-ray detector, said X-ray generator and said X-ray detector held in a facing state by a support, said X-ray photographing method comprising:
- (a) a turning controlling step of controlling a turning of said support;
- and
- (b) a light-emitter controlling step of controlling a light emitter including a plurality of light emitting elements, which is disposed on a virtual loop line surrounding a turning axis, in association with the turning of said support, so that at least one of the plurality of light emitting elements acts in a way different from at least another one of the plurality of light emitting elements at least by lighting, turning off, blinking, or color, to indicate a movement of said support or a center of a swing angle of said support.
A medical X-ray photographing apparatus comprising:
- an X-ray generator;
- an X-ray detector, the X-ray detector for emitting an electric signal in response to receiving an X-ray beam emitted from the X-ray generator;
- an X-ray axis upon which the X-ray beam is emitted;
- a support holding the X-ray generator such that the X-ray generator faces the X-ray detector;
- an image processor for generating a tomosynthesis image based on a processing of a plurality of projection images, the plurality of projection images associated with the electric signal;
- a plurality of light emitting elements;
- and
- a processor for controlling the plurality of light emitting elements to visually display an orientation of the X-ray axis and for controlling the light emitting elements so that at least one of the light emitting elements acts in a way different from at least another one of the light emitting elements at least by lighting, turning off, blinking, or color, to indicate a movement of the support or a center of a swing angle of the support.
