摘要： The present subject matter relates to systems and methods for temporal multiplexing x-ray imaging of dynamic objects with high temporal resolution and fast imaging speed. A pulsed x-ray beam can irradiate an object undergoing a range of motion such as a cyclic motion. Multiple x-ray images can be acquired at different phases within a single motion cycle or range of the object. The multiple x-ray images can be demultiplexed to produce an individual phase image. Compared to sequential imaging, temporal multiplexing x-ray imaging can achieve high temporal resolution of dynamics object in multiple phases with imaging time comparable to that of a single phase. Temporal multiplexing x-ray imaging can thus be applied to a wide variety of applications, including biomedical imaging and industrial non-destructive testing.

摘要： X-ray imaging systems and methods are provided that use temporal digital signal processing for reducing noise and for obtaining multiple images simultaneously. An x-ray imaging system can include an x-ray source adapted to generate a pulsed x-ray beam having a predetermined frequency and apply the pulsed x-ray beam to an object to be imaged. An x-ray detector can be adapted to detect x-ray radiation from the object and generate temporal data based on the x-ray radiation. A temporal data analyzer can be adapted to apply a temporal signal process to the temporal data to remove at least a portion of the temporal data having a different frequency than the predetermined frequency.
