Best 15p Cyclotron

Best 15p Cyclotron Best™ cyclotron systems are designed for optimum PET imaging compound delivery in hospitals, regional pharmacies and university research centers.  The Best 15p is a cost-effective solution to PET applications that can bring the imaging compound supply closer to the imaging center.

Positron Emission Tomography (PET), combined with computer tomography (PET-CT), has resulted in clear visualization of disease metabolism.  BCS has developed a new low-energy cyclotron system to produce positron emitters used in PET-CT.  The BEST PET 15 system includes a cyclotron, isotope production targetry, synthesis and support equipment matched to the needs of each individual customer.  In keeping with the TeamBest® mission, the BEST PET 15 system is optimum, reliable and cost effective for hospital and regional needs.  Best Cyclotron Systems is a member of the TeamBest® family and heralds the TeamBest® entry into diagnostic discipline support with complete radioisotope production systems to complement Best's 40+ year history of supporting radiotherapy.

The Best 15p is a 15 MeV proton cyclotron.  15 MeV has been selected to offer a significant 18Fluorine production yield with the investment efficiency of small power costs and low initial cost.  As the user moves to other PET radioisotopes, the energy offers adequate production yields of radioisotopes such as 18F (Fluorine) and 64Cu (Copper) with the added benefit of optimized specific activity of the product.  The cyclotron system has a small footprint and can be either installed in its own shielded room with or without local shielding (reduces radiation) or can be shielded with integrated (self) shielding.  These systems are designed for individual hospital or small regional pharmacy use.

External Production Targets

The cyclotron is supplied with two 18F production targets complete with loading and routing to the production hot cell.  Targets for 18F, 11C, 13N, 15O, 64Cu, 124I, 103Pd and 99mTc are available.
