X-ray device
First Claim
1. An X-ray device, comprising:
- an X-ray source;
a first stand alone X-ray detector for generating a first X-ray image data set of an object under examination; and
a second stand alone X-ray detector independent of the first stand alone X-ray detector for generating a second X-ray image data set of the object under examination, the second stand alone X-ray detector having a smaller detecting surface than the first stand alone X-ray detector and configured to acquire the second X-ray image data set with a higher local image resolution relative to the first X-ray image data set so that a second X-ray image generated from the second X-ray image data set shows a section of a first X-ray image generated from the first X-ray image data set, the section displayed in the second image having a higher image resolution than the same section displayed in the first image.

Abstract
An X-ray device (1) is provided including an X-ray source (8) and a first X-ray detector (9,100) for producing a first X-ray image data set of an examination object (P). A second X-ray detector (20) is provided for producing a second X-ray image data set of examination object (P) where the second X-ray detector (20) has a smaller detector surface (23) than the first X-ray detector (9,100). The second X-ray detector (20) may produce an X-ray image associated with the second X-ray image data set that has a higher local resolution than the X-ray image (12) associated with the first X-ray image data set. The second X-ray detector (20) may be movably connected with the first X-ray detector (9,100) so the second X-ray detector (20) maybe articulated upstream of the first X-ray detector (9,100).

10. An X-ray device comprising:
-
an X-ray source; a first X-ray detector for generating a first X-ray image data set of an object under examination; a second X-ray detector for generating a second X-ray image data set of the object under examination, the second X-ray detector having a smaller detecting surface than the first X-ray detector and configured to acquire the second X-ray image data set with a higher local image resolution relative to the first X-ray image data set so that a second X-ray image generated from the second X-ray image data set shows a section of a first X-ray image generated from the first X-ray image data set, the section displayed in the second image having a higher image resolution than the same section displayed in the first image; and a mechanical support device for accommodating the second X-ray detector.

11. A method of generating X-ray images based on X-ray image data sets using an X-ray device having an X-ray source and first and second X-ray detectors, the method comprising:
-
acquiring a first X-ray image data set of an object under examination by the first X-ray detector; displaying a first X-ray image generated from the first X-ray image data set on a display device; selecting a section of the first X-ray image; determining image coordinates of the section relative to the first X-ray image; aligning the second X-ray detector upstream of the first X-ray detector relative to a radiation direction from the X-ray source to the first and second X-ray detectors based on the determined image coordinates so that the second X-ray detector acquires a second X-ray image data set of the section, wherein a second X-ray image generated from the second X-ray image data set has a higher local image resolution than the first X-ray image relative to the section. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
