A Novel CT Imaging System with Adjacent Double X-Ray Sources

الملخص EN

Current computed tomography (CT) scanners rotate fast to reduce motion artifact.

X-ray tube must work in a high power to make the image clear under short exposure time.

However, the life span of such a tube may be shortened.

In this paper, we propose a novel double sources CT imaging system, which puts two of the same X-ray sources closely with each other.

The system is different from current dual source CT with orthogonal X-ray sources.

In our system, each projection is taken twice by these two sources to enhance the exposure value and then recovered to a single source projection for image reconstruction.

The proposed system can work like normal single source CT system, while halving down the working power for each tube.
