System And Method For Multi-Source X-Ray-Based Imaging

摘要

An imaging module includes a plurality of cathodes and respective gates, each cathode configured to generate a separate beam of electrons directed across a vacuum chamber and each gate matched to at least one respective cathode to enable and disable each separate beam of electrons from being directed across the vacuum chamber. A target anode is fixed within the vacuum chamber and arranged to receive the separate beam of electrons from each of the plurality of cathodes and, therefrom, generate a beam of x-rays. A deflection system is arranged between the plurality of cathodes and the target anode to generate a variable magnetic field to control a path followed by each of the separate beams of electrons to the target anode.

1. An imaging system comprising:
a platform for receiving a subject to be imaged using the imaging system; a source module arranged to deliver a beam of ionizing radiation to the subject, the source module comprising:
a vacuum chamber;at least one cathode configured to generate a beam of electrons directed across the vacuum chamber; at least one gate configured to enable and disable the beam of electrons from being directed across the vacuum chamber;
a non-rotating target anode arranged to receive the beam of electrons from each the at least one cathodes and, therefrom, generate the beam of ionizing radiation;a deflection system arranged between the cathode and the non-rotating target anode to generate a variable magnetic field to control a path followed by the beam of electrons to the target anode; and a controller configured to control operation of the at least one cathode and at least one gate to selectively enable and disable the beam of electrons from being directed across the vacuum chamber and control operation of the deflection system to change the path followed by the beam of electrons to the non-rotating target anode based.
