[An ideal imaging quality can be obtained from the evenly scattering x-ray density]

Since X-ray image quality was evaluated by the self-delivering function, the limitations in the application of fixative focus X-ray tube seem more outstanding. How to improve the quality of the x-ray image has been one of the focus problems in the field of the x-ray diagnosis. If we use the x-ray tube of the evenly scattering x-ray density as the radio source, we can get the ideal images.
