The development of compact quasimonoenergetic x-ray radiation sources based on laser Compton scattering (LCS) offers opportunities for novel approaches to medical imaging. However, careful experimental design is required to fully utilize the angle-correlated x-ray spectra produced by LCS sources. Direct simulations of LCS x-ray spectra are computationally expensive and difficult to employ in experimental optimization. In this manuscript, we present a computational method that fully characterizes angle-correlated LCS x-ray spectra at any end point energy within a range defined by three direct simulations. With this approach, subsequent LCS x-ray spectra can be generated with up to 200 times less computational overhead.
基于激光康普顿散射（LCS）的紧凑型准单能 X 射线辐射源的发展为医学成像带来了新的方法。然而，需要仔细的实验设计才能充分利用 LCS 源产生的角度相关 X 射线谱。LCS X 射线谱的直接模拟计算成本很高，并且难以在实验优化中应用。在本文中，我们提出了一种计算方法，该方法可以在三个直接模拟定义的范围内的任意端点能量下完全描述角度相关的 LCS X 射线谱。通过这种方法，可以以最高 200 倍的计算开销生成后续的 LCS X 射线谱。
