Various embodiments of a structure implemented in an X-ray imaging system are described. In one aspect, a structure implemented in an X-ray imaging system includes a silicon wafer including a first side and a second side opposite the first side. The silicon wafer also includes an array of photodiodes on the first side of the silicon wafer with the photodiodes electrically isolated from each other as well as an array of grid holes on the second side of the silicon wafer. Each grid hole of the array of grid holes is aligned with a respective photodiode of the array of photodiodes. The structure also includes a layer of scintillating material disposed over the array of grid holes on the second side of the silicon wafer. The structure further includes a layer of reflective material disposed on the layer of scintillating material.

Integrated scintillator grid with photodiodes

Apparatus, systems, and methods disclosed herein may transpose image blocks from successively-captured versions of an image according to relative movement between an image capture device and the scene being captured. The transposition may provide for alignment of the successively-captured images notwithstanding the movement. The transposed image blocks from the successive images are composited in the frequency domain by integrating frequency domain coefficients from each into a composite final image. Additional embodiments are disclosed.
