Abstract

An image displaying system includes an image processor and a display unit. The image processor moves and/or deforms a first radiographic image and a second radiographic image that has been captured after the first radiographic image such that the first radiographic image and the second radiographic image are aligned. The display unit displays the first radiographic image and the second radiographic image that have been aligned, allows one of the first and second radiographic image to be viewed by the right eye, and allows the other of the first and second radiographic image to be viewed by the left eye.

Claims

1. An image displaying system comprising:

an image processor that moves and/or deforms a first radiographic image and a second radiographic image that has been captured after the first radiographic image such that the first radiographic image and the second radiographic image are aligned and

a display unit that displays the first radiographic image and the second radiographic image that have been aligned, allows one of the first and second radiographic image to be viewed by the right eye, and allows the other of the first and second radiographic image to be viewed by the left eye.

2. An image capturing and displaying system comprising:

the image displaying system according to claim 1; and

a radiographic image capturing device that comprises;

a movable radiation source that irradiates a subject with radiation in the same position as an imaging position of the first radiographic image when capturing the second radiographic image; and

a radiation detector that detects the radiation with which the subject has been irradiated from the movable radiation source and which has passed through the subject, with a radiographic image being generated from that detected radiation.

3. An image capturing and displaying system comprising:

the image displaying system according to claim 1; and

a radiographic image capturing device that comprises;

a movable radiation source that irradiates a subject with radiation; and

a radiation detector that detects the radiation with which the subject has been irradiated from the movable radiation source and which has passed through the subject, with a radiographic image being generated from that detected radiation.

4. The image capturing and displaying system according to claim 3, wherein the radiographic image capturing device further comprises:

an object table on which the subject rests; and

a display device that displays the degree of alignment between a third radiographic image in which the subject resting on the object table has been captured and the first radiographic image.

5. The image capturing and displaying system according to claim 3, wherein the radiographic image capturing device further comprises:

an object table on which the subject rests;

an optical image capturing device that captures, from the same direction as the radiation source, the subject resting on the object table; and

a display device that displays a degree of alignment between an optical image that is obtained by the optical imaging device and the first radiographic image.

6. The image capturing and displaying system according to claim 3, wherein the radiographic image capturing device further comprises a display device that displays the first radiographic image.

7. The image capturing and displaying system according to claim 6, wherein the display device comprises a projection device that projects the first radiographic image onto an object table on which the subject rests.

8. The image capturing and displaying system according to claim 6, wherein the display device comprises a projection device that projects the first radiographic image onto a compression plate that compresses the subject.

9. The image capturing and displaying system according to claim 2, further comprising a storage unit that stores position information of the imaging position in the first radiographic image,

wherein the radiographic image capturing device references the position information to determine the imaging position in the second radiographic image when capturing the second radiographic image.

10. The image capturing and displaying system according to claim 2, further comprising an input unit to which is inputted position information of the imaging position in the first radiographic image,

wherein the radiographic image capturing device references the position information to determine the imaging position in the second radiographic image when capturing the second radiographic image.

11. The image displaying system according to claim 1, wherein the image processor performs alignment of the first radiographic image and the second radiographic image by transforming at least one of the first radiographic image and the second radiographic image.

12. The image displaying system according to claim 11, wherein the transformation includes any of

comprehensive alignment including at least one of rotation, parallel translation and enlargement/reduction with respect to the entirety of the at least one image,

local alignment resulting from nonlinear distortion transformation based on a corresponding positional relationship that has been obtained by template matching per local region, and

a combination of these.
