Systems and related methods for stationary digital chest tomosynthesis (s-DCT) imaging

Systems and related methods for stationary digital chest tomosynthesis (s-DCT) imaging are disclosed. In some aspects, systems include a stationary x-ray source array with an array of x-ray pixels configured to generate x-ray beams at different viewing angles relative to a subject to be imaged that is stationary, a stationary area x-ray detector configured to record x-ray projection images of the subject, a physiological gating apparatus for monitoring at least one physiological signal of the subject and defining a physiological phase and a time window based on the at least one physiological signal, and a computing platform configured to activate the x-ray pixels based on the physiological phase and the time window and upon receipt of the at least one physiological signal from the physiological gating apparatus in order to synchronize x-ray exposure with the at least one physiological signal of the subject.
