| 摘要 |
The present invention relates to an imaging apparatus for determining an image of a region of interest, wherein a motion generation unit (1, 7, 8) moves the radiation source (2) and a region of interest relative to each other along a first trajectory (32), while a detection unit (6) detects first detection data. A reconstruction data determination unit (12) determines reconstruction data among the first detection data and a second trajectory determination unit (13) determines a second trajectory (32) depending on the reconstruction data. After that the motion generation unit (1, 7, 8) moves the radiation source (2) and the region of interest relative to each other along the second trajectory (32), while the detection unit (6) detects second detection data. The reconstruction data and the second detection data are used by a reconstruction unit (14) for reconstructing an image of the region of interest. |
