  • System and method for compact laminography utilizing microfocus transmission x-ray source and variable magnification x-ray detector
    Patent number: 11992350
    Abstract: An x-ray computed laminography imaging system includes a transmission x-ray source configured to generate x-rays, at least some of the x-rays propagate along an x-ray propagation axis through a region of interest of an object. The system further includes a stage assembly configured to rotate the object about a rotation axis extending through the region of interest. The system further includes at least one x-ray detector configured to intercept at least some of the x-rays propagating along the x-ray propagation axis. The at least one x-ray detector includes a scintillator, at least one optical lens, and two-dimensional pixelated imaging circuitry. The scintillator has a thickness that is substantially parallel to the x-ray propagation axis and the at least one optical lens is configured to receive visible light from the scintillator and to focus the visible light into a two-dimensional image.
