利用正电子示踪成像系统（PETIS）结合（CO2）-C-11气体示踪剂，对水稻光合作用及随后的光合产物转运和卸载过程中的碳动力学进行了全株成像研究。以大豆（Glycine max traditional Jack）植株为实验对象，证实了所获得的动态PETIS图像数据遵循总碳守恒定律。因此，建议PETIS技术是一个可行的非侵入性和定量的解决方案，研究整个植物的碳动态在环境和农业研究。(C)2010 Elsevier B. V.保留所有权利。
Whole-plant imaging for studying the complete carbon kinetics involved in photosynthesis and subsequent photoassimilate translocation and unloading was achieved using a positron-emitting tracer imaging system (PETIS) in combination with (CO2)-C-11 gas tracer. In an experiment with a soybean (Glycine max cultivar Jack) plant, it was confirmed that the dynamic PETIS image data obtained followed the conservation law for total carbon. Thus, the proposed PETIS technique is a feasible noninvasive and quantitative solution to study the carbon dynamics over an entire plant in environmental and agricultural studies.
