Abstract
Methods, systems, and apparatus for performing spectral tomographic reconstruction of an object. The imaging system includes a power source that is configured to provide a variable high voltage. The imaging system includes a distributed X-ray source. The distributed X-ray source includes an array of X-ray emitters that allows fast switching “ON” and “OFF” using X-ray emitter grid electrode. The distributed X-ray sources is configured to generate an X-ray beam with an energy spectrum based on the variable high voltage and uses additional X-ray filters. The imaging system includes a controller. The controller is configured to operate synchronously with the change of the variable high voltage. The controller is configured to control a timing of when to engage an X-ray emitter of the array of X-ray emitters of the distributed X-ray source based on a predefined firing pattern.
