Abstract:
1. A system for creating a rapid sequence of X-ray images of a subject, comprising: an X-ray source; a collimator for collimating X-ray photons from the X-ray source into a fan beam having a center portion and a wing portion, a measurement selected from a width and a diameter of the center portion being larger than a width of the wing portion; apparatus for rotating the collimator to spin the fan beam about an axis extending from the X-ray source to a detector, wherein the wing portion of the fan beam intermittently illuminates at least a portion of the subject disposed between the collimator and the detector; the detector being capable of receiving the fan beam and for generating electronic information therefrom; and an image processor for constructing a rapid sequence of images of the subject from the electronic information.
