Abstract
Dual-beam x-ray tomography systems are paving the way for new experimental procedures, such as multi-resolution and multi-energy imaging, where synchronous acquisitions are essential. However, in such systems, cross-detector scatter between the detecting devices can occur as the two beamlines operate simultaneously. This paper proposes a new affine image transformation model of each projection to correct for these cross-detector scatter issues. A toy tomography test case is presented to assess the feasibility and performance of the proposed correction method.
双光束 X 射线断层成像系统为多分辨率和多能量成像等新实验程序铺平了道路,在这些程序中,同步采集是必不可少的。然而,在这类系统中,由于两条光束线同时工作,探测设备之间会产生交叉探测器散射。本文提出了一种新的每个投影的仿射图像变换模型,以纠正这些交叉探测器散射问题。本文介绍了一个玩具层析成像测试案例,以评估所提出的校正方法的可行性和性能。
