What Best Cyclotron Systems does

Best Cyclotron Systems (BCS) designs, manufactures, and services commercial cyclotrons for the nuclear medicine and radiotherapy sectors. The company is a trade name (DBA) of Best Theratronics Ltd., itself a subsidiary of Best Medical International within the privately held TeamBest Global group of companies founded and led by Krishnan Suthanthiran. BCS was established in Springfield, Virginia for the design of cyclotrons, with manufacturing and testing conducted at the Best Theratronics facility in Ottawa, Ontario, Canada and registered offices in Vancouver, BC.

The product portfolio spans six energy domains from a 7.5 MeV self-shielded B-100 system to a 70 MeV Best 70p cyclotron, including the B-11 (11 MeV), BG-95 (9.5 MeV self-shielded), Best 15p (15 MeV), Best 25p (25 MeV), and Best 35p (35 MeV), plus variable-energy and multi-particle variants such as the Best 6p and B25u/35adp (alpha/deuteron/proton). All systems use negative hydrogen ion (H-) acceleration technology with multi-beam extraction; the B-100 and BG-95 are self-shielded compact designs enabling installation adjacent to PET/CT equipment without separate shielded rooms. Patent-pending developments include 70-200 MeV proton therapy, 3-90 MeV neutron production, 1-3 MeV deuterons for materials analysis, and a 100 MeV variable energy therapy system.

BCS generates revenue primarily through turnkey capital equipment sales, facility design and implementation services, and ongoing maintenance and emergency repair support via the TeamBest network. Customers include individual hospitals requiring in-house PET radioisotope production, regional radiopharmacies producing commercial quantities of PET and SPECT compounds, university research centers, and government laboratories (notably INFN in Italy). Sales cycles are long, driven by international tenders, conference presence at SNMMI/ASTRO/AAPM/ACRO/ECMP, and direct enterprise engagement.

Emerging players

• ProTom International: Develops single-room proton therapy systems - emerging adjacent player in particle therapy equipment overlapping with BCS's patent-pending 70-200 MeV proton therapy platform.
• Mevion Medical Systems: Develops compact proton therapy systems - an emerging adjacent player to BCS's announced 100 MeV variable-energy proton therapy platform, focused on oncology use cases.
• Ionetix Corporation: U.S.-based emerging manufacturer of compact cyclotrons targeting Tc-99m and other radioisotope supply chain gaps - an emerging competitor in adjacent compact-cyclotron niches to BCS's B-100/BG-95 products.

Direct peers

• IBA (Ion Beam Applications): World's largest dedicated manufacturer of cyclotrons and integrated PET radioisotope production solutions for hospitals and radiopharmacies - directly overlapping with BCS in product category, customer base, and turnkey business model.
• Advanced Cyclotron Systems (ACSI): Canadian-based manufacturer of commercial cyclotrons ranging from 8 MeV to 30 MeV for PET and SPECT radioisotope production, serving hospitals and research centers with a directly comparable product line to BCS.
• Best ABT Molecular Imaging: Sister company under TeamBest that also manufactures cyclotrons; merged into BCS in January 2022 but the brand remains an internal peer for product portfolio comparisons within TeamBest distribution.

Broad incumbents

• GE HealthCare: Sells the PETtrace family of cyclotrons for medical isotope production as part of a much broader medical imaging portfolio (MRI, CT, PET scanners) - overlapping technology in cyclotrons but as part of a wider medical imaging incumbent offering.
• Sumitomo Heavy Industries: Manufactures cyclotrons and high-energy particle therapy systems (proton therapy) as part of a much larger industrial conglomerate - a broad incumbent in adjacent particle accelerator and nuclear medicine equipment categories.
• Siemens Healthineers / Varian: Post-Varian acquisition, a major incumbent in radiation therapy and medical imaging; competes with BCS-adjacent proton therapy products and operates broader imaging equipment portfolios.
• SHI-AT (Sumitomo Heavy Industries Accelerator Technology): Specialized division of Sumitomo Heavy Industries focused on medical accelerators and PET cyclotrons - directly overlapping with BCS in isotope-production cyclotrons but as part of a much larger industrial group.
