In today's technology, patients who might have life-threatening illnesses are required to undergo a number of tests such as a PET (Positron Emission Tomography) scan or a SPECT (Single-Photon Emission Computed Tomography) scan in order to look for a particular disease, or check if their organs are functioning properly respectively. Both PET and SPECT scanners require exposing the patient to a small amount of radiation, which enables devices to capture an image of the patient's internal organs that are then analyzed by medical specialists. PET scans detect gamma rays with a specific energy of 511 keV, while SPECT can only detect gamma rays at relatively lower energies because collimators used in SPECT become transparent for high energy gamma-rays. Performing separate PET and SPECT scans is both time consuming and exposes the patient to increased levels of radiation.

A team led by Gunma University Heavy Ion Medical Center Special Professor Takashi Nakano, a pioneer in heavy particle beam therapy in Japan, has been working to combine these procedures. They worked in collaboration with teams at Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), led by Professor Tadayuki Takahashi, the National Institutes for Quantum and Radiological Science and Technology, led by Naoki Kawachi, and the Japan Aerospace Exploration Agency (JAXA), led by Assistant Professor Shin Watanabe, and completed a successful clinical trial using a newly-developed imaging diagnosis device called a Compton camera that makes...
