  • Patent number: 11469071
    Abstract: The rotatable anode of a rotating anode X-ray source has demanding requirements placed upon it. For example, it may rotate at a frequency as high as 200 Hz. X-ray emission is stimulated by applying a large voltage to the cathode, causing electrons to collide with the focal track. The focal spot generated at the electron impact position may have a peak temperature between 2000° C. and 3000° C. The constant rotation of the rotating anode protects the focal track to some extent, however the average temperature of the focal track immediately following a CT acquisition protocol may still be around 1500° C. Therefore, demanding requirements are placed upon the design of the rotating anode. The present application proposes a multi-layer coating for the target region of a rotating X-ray anode which improves mechanical resilience and thermal resilience, whilst reducing the amount of expensive refractory metals required.

  • Patent number: 11430118
    Abstract: In one embodiment, an X-ray inspection system may capture one or more X-ray images for samples of interest processed by a first tool. The X-ray inspection system may be inline with the first tool and have an inspection speed of 300 mm2 per minute or greater. The system may determine, in real-time, metrology information related to the samples of interest based on the X-ray images. The metrology information may indicate that a sample parameter associated with the samples of interest is outside of a pre-determined range. The system may provide instructions or data to one or more of the first tool or one or more second tools to adjust process parameters associated with the respective tools based on metrology information. The adjusted process parameters may reduce a processing error probability, of the respective tool for processing subsequent samples, related to the sample parameter being outside of the pre-determined range.
