The Compton camera technique is a well-known method of visualizing the distribution of radiation sources that emit gamma rays with energies of approximately 1 MeV. One major disadvantage of this technique is that the reconstructed image is degraded owing to the appearance of artificial uneven structures caused by accumulating rings estimated from each event. In this study, we demonstrated that we can easily achieve shift-invariant gamma-ray imaging with a drastic reduction in these artificial uneven structures by rotating the Compton camera during the measurement while also applying image sharpening techniques based on the filtered back-projection algorithm used in computed tomography

通过向高灵敏度全向康普顿相机添加探测器旋转功能来实现位移不变伽马射线成像

康普顿相机技术是一种众所周知的可视化辐射源分布的方法，这些辐射源发出能量约为 1 MeV 的伽马射线。这种技术的一个主要缺点是重建的图像由于从每个事件估计的累积环引起的人工不均匀结构的出现而退化。在这项研究中，我们证明了通过在测量过程中旋转康普顿相机，同时还应用基于所使用的滤波反投影算法的图像锐化技术，我们可以轻松地实现平移不变伽马射线成像，并大幅减少这些人工不均匀结构。在计算机断层扫描中
