1. An x-ray treatment system comprising:
an electron beam generator configured to generate an electron beam;
an x-ray treatment head comprising a pixel source cell array including a plurality of pixel source cells, each of the plurality of pixel source cells comprising side walls defining an x-ray transmissive interior of the pixel source cell, the side walls comprising an x-ray absorptive material, the pixel source cells further comprising a target element that, when impacted by the electron beam, generates x-ray photon radiation within the x-ray transmissive interior; and
an electron beam control system comprising a controller configured to:
receive a treatment plan for a lesion to be treated;
select, based on the received treatment plan, one or more pixel source cells out of the plurality of pixel source cells, the one or more pixel source cells depicting a shape of the lesion such that each of one or more edge pixel source cells located at a perimeter of the selected one or more pixel source cells includes a part of a perimeter of the lesion;
determine, based on the received treatment plan, at least one of a direction and intensity of the electron beam to be delivered to each of the selected one or more pixel source cells; and
transmit data to the electron beam generator and the x-ray treatment head, the data including the selected one or more pixel source cells and the determined at least one of the direction and the intensity for each of the selected one or more pixel source cells.
