| 内容記述 | Positron Emission Tomography (PET) is one of the most significant medical applications of positrons, enabling noninvasive imaging of physiological and biochemical processes in living organisms. It is widely used in clinical practice, clinical research, and a broad range of other research fields, including preclinical studies [1]. PET plays a crucial role in the early detection of cancer and neurodegenerative diseases such as Alzheimer’s disease, leveraging positron annihilation to generate high-resolution metabolic images.Despite its widespread adoption, PET technology continues to evolve, driven by ongoing research and development efforts worldwide to enhance its fundamental performance and expand its applications. In this presentation, we introduce next-generation PET systems and detector technologies being developed at QST to advance the medical utilization of positrons. Figure 1 highlights the representative developments: a recently commercialized helmet-type PET system for dedicated brain imaging (Figure 1a) [2] and the world’s first open PET system OpenPET which has recently entered clinical research for carbon-ion cancer therapy (Figure 1b) [3,4], whole gamma imaging (WGI) which integrates Compton imaging [5] and PET to enable imaging of various gamma rays (Figure 1c) [6,7], and Quantum PET which aims to visualize positron lifetime, particularly the positronium lifetime distribution within living organisms [8-10] (Figure 1d).These advancements enhance imaging capabilities for specific medical and research applications, further expanding the role of positrons in medical imaging.Figure 1 Representative developments at QST: (a) Helmet-type PET, commercialized for brain imaging, reprinted from [2] (CC BY 4.0); (b) human-scale OpenPET system, reprinted from [3] (CC BY 4.0); (c) WGI prototype, ©2020 Institute of Physics and Engineering in Medicine, reprinted with permission from [6]; (d) conceptual illustration of Quantum PET.References[1] S.
