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 typically involves complex and precise movements of a grating for each image, challenging in applications like medical computed tomography that demand rapid gantry rotation and acquisition of numerous projection images in less than a second. The innovation of this technology lies in its ability to perform electronic fringe scanning without any moving parts, offering a more efficient, cost-effective, and less complex solution to capturing high-quality phase-contrast images.
