Systems and methods for temporal multiplexing X-ray imaging

A method of temporal multiplexing x-ray imaging of a dynamic object, the method comprising:

• (a) passing a sequenced combination of x-ray beam pulses through an object undergoing cyclic motion, each of the x-ray beam pulses corresponding to a temporal phase of the cyclic motion;
• (b) detecting the x-ray beam pulses;
• (c) generating a plurality of multiplexed x-ray images of the combination of x-ray beam pulses passed through the object, each of the plurality of multiplexed x-ray images being generated from the combination of x-ray beam pulses passed through the object during different cycles of the cyclic motion;
• and
• (d) demultiplexing the plurality of multiplexed x-ray images to generate an x-ray image of the object for each temporal phase.

An x-ray imaging system comprising:

• a single-beam x-ray source operable for passing a pulsed x-ray beam through an object undergoing cyclic motion;
• an x-ray detector;
• a controller in communication with the x-ray source and the object and being operable to generate a sequenced combination of x-ray beam pulses from the x-ray source and acquire one or more multiplexed x-ray images of the object undergoing cyclic motion, each of the x-ray beam pulses corresponding to a temporal phase of the cyclic motion;
• an imaging processing unit operable to de-multiplex the multiplexed images to obtain images of the object at different temporal phases of the cyclic motion.
