More Information
Summary:A system for obtaining an image includes a processor for receiving a projection image, processing the projection image to obtain a filtered image, applying a first factor for the projection image to obtain a first weighted image, applying a second factor for the filtered image to obtain a second weighted image, and obtaining a corrected image using the first and second weighted images, and a medium for storing the corrected image. A method of processing an image includes receiving a projection image, processing the projection image to obtain a filtered image, and determining a corrected image by applying a first factor for the projection image and applying a second factor for the filtered image. A method for obtaining an image includes determining a factor, using the factor to control a radiation source, and using the factor to reduce noise in an image generated using the radiation source.
