Objectives: This paper presents the prospects for increasing the availability of PET diagnostics by combining low-cost, lightweight and easily portable modular J-PET with the Ti/Sc generator. Methods: J-PET is constructed based on the low-cost axially arranged plastic scintillators that may enable the construction of PET scanners 5 to 10 times less expensive compared to current PET systems, which are based on crystal scintillators. Development of the radionuclide Ti/Sc generator with the 60-year half-lifetime would enable long-term onsite production of Sc labelled radiopharmaceuticals, eliminating the need for extensive and costly infrastructure typically associated with nuclear medicine. Presently applied Ge/Ga generators with the 270 days half- -lifetime require renewal every year. The Ti/Sc generator could, in principle, be purchased once every half century. Results: The lightweight and portable J-PET scanner, combined with the Ti/Sc generator, can be deployed in remote and underserved regions, thus democratising access to advanced medical-imaging techniques. Conclusions: This novel concept shows the transformative potential of combining innovative J-PET technology with the Ti/Sc generator to make advanced diagnostics more accessible and affordable worldwide, especially benefiting millions of patients in low- and medium-income countries, and driving further innovations in medical imaging.
