摘要：

An imaging system includes at least two x-ray sources, an x-ray detector assembly and an attenuation filter. The at least two x-ray sources are displaced along a z-axis and configured to alternately emit x-ray beams. The x-ray detector assembly is configured to detect the x-ray beams. The attenuation filter is mounted proximate the at least two x-ray sources and is configured to provide different amounts of x-ray attenuation to the x-ray beams along the z-axis.
