The present invention provides systems and methods for x-ray imaging. In some embodiments, an aperture, or a plurality thereof, are configured to have image transfer functions lacking a zero within a usable spatial frequency range. In further embodiments, the image transfer function is determined according to the shape of the aperture and the usable spatial frequency range is determined according to a usable signal to noise ratio.
