Abstract
A tomosynthesis system has an x-ray source with an addressable array of electron emitting sections on the cathode. The x-ray source moves rotationally about an imaging target, such as a breast. During the rotation, x-rays are emitting from the x-ray source while the x-ray source continues to move. During the emission of x-rays, different subsets of electron-emitting sections of the addressable array are activated to compensate for movement of the x-ray source. By activating the different subsets of electron-emitting sections, an effective focal spot of the x-ray position appears to retain the same shape, size, and position from the perspective of the imaging target, despite movement of the x-ray source itself.
