虽然大多数Radon变换成像应用都涉及环境空间光滑子流形上的积分,但最近出现了积分曲面为锥形的重要情况。其中三个应用是单散射光学断层扫描、康普顿相机医学成像和国土安全。尽管有相似的积分曲面,但与这些模态相关的数据和反问题差异很大。在本文中,我们简要概述了康普顿相机成像中出现的数学问题。特别强调了探测器的超定数据和灵活的几何形状。对于详细的结果,以及其他方法(如较小维度的数据或探测器的限制几何),读者被引导到相关的出版物。
While most of Radon transform applications to imaging involve integrations over smooth sub-manifolds of the ambient space, lately important situations have appeared where the integration surfaces are conical. Three of such applications are single scatter optical tomography, Compton camera medical imaging, and homeland security. In spite of the similar surfaces of integration, the data and the inverse problems associated with these modalities differ significantly. In this article, we present a brief overview of the mathematics arising in Compton camera imaging. In particular, the emphasis is made on the overdetermined data and flexible geometry of the detectors. For the detailed results, as well as other approaches (eg smaller-dimensional data or restricted geometry of detectors) the reader is directed to the relevant publications.
