| 摘要 |
The preset invention relates to a source-side monitoring device (SSRD)(50) comprising a detector module assembly (102) and a monitoring lens (100) connected to the detector module assembly. The detector module assembly and the monitoring lens are positioned close to an x-ray source (12). The monitoring lens comprises multiple slits (140, 142) to receive x-rays (14) from the x-ray source. The detector module assembly detects the x-rays transferred through the slits and generates information to trace a focal point (200) of the x-ray source.
