  • Patent number: 11662321
    Abstract: Systems and methods for scatter correction of x-ray images are provided. A scatter image of an object can be corrected using partial-scatter free images acquired using an aperture plate. The plate is positioned between an object and a radiation detector and includes apertures in a grid. The original x-rays pass through the apertures and scattered x-rays can be blocked by the aperture plate. The aperture plate can be moved to different positions, allowing partial scatter-free images to be acquired at each position of the aperture plate. A full scatter-free image can be generated by combining partial scatter-free images. The scatter and scatter-free images can be further used to train scatter correction models.
