摘要
A method and system for performing fluoroscopic imaging of a subject has high temporal and spatial resolution in a center portion of the captured dynamic images. The system provides for reduced X-ray dose to the patient associated with that part of the X-ray beam associated with a peripheral portion of the captured images although temporal, and in some embodiments spatial, resolution is reduced in the peripheral portion of the image. The system uses a rotating collimator to produce an X-ray beam having narrow wing portions associated with the peripheral portions of the image, and a broader central region associated with the high resolution center portion of the images.
