X-ray diagnostic apparatus
View Patent ↗To provide an X-ray diagnostic apparatus capable of providing a stereoscopic perspective image in the form of a video image while reducing exposure dose. An X-ray diagnosis apparatus according to an embodiment includes: a main row X-ray source group including a plurality of X-ray sources; an X-ray detection section disposed opposite to the X-ray sources; a timing controller that controls a switching timing of the X-ray sources and an X-ray generation position; an image acquisition section that acquires output image data from the X-ray detection section in synchronization with the switching timing; and a stereoscopic image display section that displays the output image data as a plurality of images having different disparities.
1. An X-ray diagnosis apparatus comprising:
a main row X-ray source group including a first plurality of X-ray sources arranged in an azimuth direction;
a sub row X-ray source group which is arranged at a position shifted in an elevation direction from the main row X-ray source group, wherein the sub row X-ray source group includes a second plurality of X-ray sources arranged in the azimuth direction;
an X-ray detection section disposed opposite to the X-ray sources;
a timing controller that controls a switching timing of the X-ray sources and an X-ray generation position;
an image acquisition section that acquires output image data from the X-ray detection section in synchronization with the switching timing;
a face tracking section that detects a line of sight position of an observer with respect to a stereoscopic image display section;
an interpolation section that generates a plurality of images with different disparities corresponding to the line of sight position by performing interpolation using the output image data from the X-ray detection section corresponding to the X-ray sources included in the main row X-ray source group and sub row X-ray source group; and
the stereoscopic image display section that displays the plurality of images having different disparities, wherein
the stereoscopic image display section is a liquid crystal panel capable of emitting light in different directions from a panel surface, wherein the liquid crystal panel emits the plurality of images having different disparities in respective ones of the different directions,
a number of the X-ray sources of the sub row X-ray source group is less than a number of the X-ray sources of the main row X-ray source group, and
the interpolation section generates interpolated images in the azimuth direction by using a portion of the output image data corresponding to the X-ray sources of the sub row X-ray source group, and thereafter the interpolation section generates the plurality of images by performing interpolation in the elevation direction using the interpolated images and the output image data corresponding to the X-ray sources of the main row X-ray source group and sub row X-ray source group.
2. The X-ray diagnosis apparatus according to claim 1 , further comprising a distortion correction section that corrects image distortion of the output image data from the X-ray detection section.
3. The X-ray diagnosis apparatus according to claim 2 , further comprising an image recording section that records therein the image data output from one of the image acquisition section and distortion correction section.
4. The X-ray diagnosis apparatus according to claim 2 , further comprising an image recording section that records therein the image data output from one of the image acquisition section, distortion correction section, and interpolation section.
5. The X-ray diagnosis apparatus according to claim 4 , wherein
the image recording section stores therein the plurality of images with different disparities generated by the interpolation section.
6. The X-ray diagnosis apparatus according to claim 1 , wherein
the interpolation section generates two images having different disparities corresponding to left and right eyes of the observer in the line of sight position thereof detected by the face tracking section by performing interpolation using output images of the X-ray detection section corresponding to the X-ray sources adjacent to the line of sight position.
7. The X-ray diagnosis apparatus according to claim 6 , further comprising an X-ray source selection section that selects the X-ray sources adjacent to the line of sight position for switching.
8. The X-ray diagnosis apparatus according to claim 7 , further comprising:
a distortion correction section that corrects image distortion of the output image data from the X-ray detection section; and
an image recording section that records therein the image data output from one of the image acquisition section, distortion correction section, and interpolation section.
9. The X-ray diagnosis apparatus according to claim 8 , wherein
the image recording section stores therein image data of the X-ray sources selected by the X-ray source selection section.
10. The X-ray diagnosis apparatus according to claim 9 , wherein
the image recording section stores the two images with different disparities generated by the interpolation section.
11. The X-ray diagnosis apparatus according to claim 3 , wherein
the distortion correction section corrects image distortion of the recorded image data.
12. The X-ray diagnosis apparatus according to claim 3 , wherein
the interpolation section generates a plurality of images with different disparities by performing interpolation using the image data acquired from one of the image recording section and distortion correction section.
