摘要

康普顿成像是一种新兴的方法来可视化X射线和伽马射线源。尽管康普顿成像的应用越来越广泛，但大多数传统的图像重建方法都没有在每个生成的图像上定义不确定性。我们提出了一种新的康普顿成像方法，命名为Langevin Compton成像，它以统计上有充分根据的方式定义了康普顿图像的不确定性。我们定量地评估图像特征的统计显著性，例如多个源峰的存在。此外，我们的方法使我们能够估计源峰之间的强度比。

Langevin Compton Imaging: A new method of visualizing radioactive sources based on Markov chain Monte Carlo

Compton imaging is an emerging method to visualize X- and gamma-ray sources. Regardless of the expanding use of the Compton imaging, most conventional image reconstruction methods do not derive uncertainties that should be defined on each resulting image. We propose a new Compton imaging method, named Langevin Compton Imaging, that defines uncertainties of Compton images in a statistically well-founded manner. We quantitatively evaluate the statistical significance of image features, such as the presence of multiple source peaks. Moreover, our method enables us estimate the intensity ratio between source peaks.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
