SYSTEMS AND RELATED METHODS FOR STATIONARY DIGITAL CHEST TOMOSYNTHESIS (S-DCT) IMAGING

摘要

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.

1. A system for stationary x-ray digital tomosynthesis imaging, the system comprising:
a stationary x-ray source array comprising an array of spatially distributed 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 positioned substantially parallel to a plane of the x-ray source array and configured to record x-ray projection images of the subject from the different viewing angles for tomosynthesis reconstruction; a physiological gating apparatus for monitoring at least one physiological signal of the subject, the physiological gating apparatus defining a physiological phase and a time window based on the at least one physiological signal during which the x-ray projection images of the subject from the different viewing angles are acquirable; and a computing platform comprising at least one hardware processor and a memory, the computing platform being 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.
