Electronic Fringe Scanning for the Improvement of Medical Imaging Technology
This technology includes an electronic method for fringe scanning in grating-based phase-contrast imaging, which enhances x-ray phase-contrast imaging. Traditional methods use high-density gratings and require fine grating fringes, finer than the detector's resolution, necessitating fringe scanning to obtain phase-contrast information. This process...
