| 摘要 |
<p>The invention relates to a phase contrast x-ray tomography device, comprising an electron gun (44) having a downstream deflector coil (52). The x-ray beam (56) is guided by the deflector coil (54) on a circular path over a target (58), which is marginally tilted towards a plane positioned vertically on the device axis. The x-ray beam (62) generated at focal spot F of the electron beam (56) crosses an object (70) and arrives at a detector line (68) via a phase grating (64) and an amplitude grating (66)</p> |
