The principle, data analysis methods, and its applications for brain research into positron emission tomography

Abstract

<p indent="0mm">Positron emission tomography (PET) is a typical application for nuclear science and technology in biomedicine. A positron-labeled compound is used as a tracer during PET imaging, which traces the corresponding physiological or biochemical processes in the organ being studied. The distribution of the tracer in the organ is displayed via tomographic imaging, which reflects the biological functional status of the organ under certain conditions. This paper will systematically introduce the principles of PET imaging, progress in the data processing methods, and applications for brain imaging.
