Characterization of aberrations in image-intensified fluoroscopy.
A procedure is developed for characterizing and measuring the distortion and intensity variations which are present in x-ray image-intensifier systems. These effects often seriously limit the usefulness of such systems, and the results here make possible an evaluation and comparison of competing intensifier instruments.
