Abstract

Methods, systems, and computer program products for multiplexing computed tomography are disclosed. According to one aspect, the subject matter described herein can include illuminating an object with a plurality of x-ray beams from a plurality of viewing angles, wherein each x-ray beam has a distinct waveform; detecting the x-ray intensities of the plurality of pulsed x- ray beams as a function of time, and extracting individual projection image data from the detected x-ray intensities based on the distinct waveforms of the x-ray beams for combining the projection image data to generate three- dimensional tomographic image data of the object.
