Photograph of GREI-II (IMAGE) RIKEN Caption Dr. Shuichi Enomoto, Dr. Shinji Motomura and colleagues, RIKEN Center for Life Science Technologies, have developed a gamma-ray imaging camera enabling them to detect the gamma-rays emitted by multiple bio-metal elements in the body and study their behavior. Their second prototype of the system, called GREI–II and presented today in the Journal of Analytical Atomic Spectrometry, enables them to visualize multiple bio-metal elements more than 10 times faster than before, and to do so simultaneously with positron emission tomography (PET).
