Radiotracer imaging technologies enable us to know live the physiological function in the plant body. Serial images of the radiotracer can be used to indicate the changing distribution of constituent behavior within a living plant system and to describe the dynamics and kinetics of a substance in an intact plant. X-rays and Gamma-rays emitted from the radiotracer in a plant almost completely penetrate the body, and the image data obtained using them can potentially be used to quantitatively analyze physiological function parameters. This study is realized in the field of plant science to investigate kinetics of plant nutritions and environmental pollutions on use of a multi-element imaging system of a Compton camera for simultaneous multi-RI tracer imaging in intact plant.
