PET has the potential to verify charged particle therapy in vivo, reducing uncertainty in particle range and improving treatment accuracy. However, biological washout and the short half-life of positron emitters generated by the treatment beam mean that scans must be performed during or shortly after treatment.
In a new development, a unique transformable PET system that images both during and after irradiation has proven feasible. The miniature OpenPET prototype was developed by researchers from the National Institute of Radiological Sciences (NIRS) in Chiba, Japan. Read more.
