Abstract

A radiation imaging apparatus includes: a radiation irradiating apparatus that emits radiation onto a subject; a photography unit that photographs the subject to obtain a photographed image of the subject; and a radiation detector that generates radiation images of the subject, provided with a marker that represents identifying information of the radiation detector on the side thereof that includes a radiation detecting surface. The marker of the radiation detector is detected. The identifying information of the radiation detector is obtained from a marker in the case that the marker is detected.

First claim

What is claimed is:

1 . A radiation imaging apparatus, comprising:
a radiation source that emits radiation onto a subject; a photography unit for photographing the subject to obtain a photographed image of the subject; and an identifying information obtaining unit for detecting a marker, provided on a radiation detector that detects radiation which has passed through the subject and generates a radiation image of the subject, that represents identifying information of a radiation detector, the marker being provided on the side of the radiation detector that includes a radiation detecting surface, and obtaining the identifying information of the radiation detector from the marker in the case that the marker is detected.

2 . A radiation imaging apparatus as defined in claim 1 , wherein:
the radiation source and the photography unit are provided as an integrated unit.

3 . A radiation imaging apparatus as defined in claim 1 , further comprising:
an identifying unit for identifying the radiation detector based on the identifying information.

4 . A radiation imaging apparatus as defined in claim 1 , further comprising:
the radiation detector.

5 . A radiation imaging apparatus as defined in claim 4 , wherein:
the marker is provided at a portion at the side of the detecting surface other than a detection region that detects radiation.

6 . A radiation imaging apparatus as defined in claim 4 , wherein:
a surface of the radiation detector that includes the detection region that detects radiation is of a rectangular shape; and each of a plurality of markers is provided at least at one of the vicinities of different edges and the vicinities of different corners of the surface that includes the detection region.

7 . A radiation imaging apparatus as defined in claim 4 , wherein:
the marker is a bar code.

8 . A radiation imaging apparatus as defined in claim 4 , wherein:
the marker represents different types of radiation detectors using different colored information as the identifying information.

9 . A radiation imaging apparatus as defined in claim 4 , wherein:
the marker is a light emitting device; and the identifying information is represented by at least one of the color of light, the lighting pattern of the light, and the blinking pattern of the light emitted by the light emitting device.

10 . A radiation imaging apparatus as defined in claim 9 , wherein:
at least one of the color of light, the lighting pattern of the light, and the blinking pattern of the light emitted by the light emitting device represents detector information of the radiation detector.

11 . A radiation imaging apparatus as defined in claim 1 , further comprising:
positional relationship obtaining means for obtaining the relative positional relationship between the radiation detector and the radiation source based on at least one of the size and the shape of a marker within the photographed image, in the case that the marker is detected.

12 . A radiation imaging apparatus as defined in claim 1 , wherein:
the surface of the radiation detector opposite the detecting surface is provided with another marker that represents that the surface is that which is opposite the detecting surface.

13 . A method for controlling a radiation imaging apparatus equipped with a radiation source that irradiates radiation onto a subject and a photography unit for photographing the subject to obtain a photographed image of the subject, comprising:
detecting a marker that represents identifying information of a radiation detector that detects radiation which has passed through the subject and generates a radiation image of the subject, provided on the side of the radiation detector at the side of a radiation detecting surface, from the photographed image; and obtaining the identifying information of the radiation detector from a marker in the case that the marker is detected.

14 . A non-transitory recording medium having recorded therein program that causes a computer to execute a method for controlling a radiation imaging apparatus equipped with a radiation source that irradiates radiation onto a subject and a photography unit for photographing the subject to obtain a photographed image of the subject, the program comprising the procedures of:
detecting a marker that represents identifying information of a radiation detector that detects radiation which has passed through the subject and generates a radiation image of the subject, provided on the side of the radiation detector at the side of a radiation detecting surface, from the photographed image; and obtaining the identifying information of the radiation detector from a marker in the case that the marker is detected.
