Medical X-ray photographing apparatus and X-ray photographing method
First Claim
1. 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, whereinsaid 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.

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.

15. 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. - View Dependent Claims (16, 17, 18, 19)

20. 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. - View Dependent Claims (21)
