What Medical Physics Services does

Medical Physics Services, LLC (MPS), founded in 2004 by Gloria P. Beyer, Ph.D., DABR, and headquartered in Coral Gables, Florida, provides independent commissioning and clinical implementation services for radiation therapy equipment. Its core service lines are commissioning of linear accelerators (including Varian TrueBeam, Edge, Halcyon, and VitalBeam platforms), small-field and stereotactic commissioning for SRS and SBRT programs, ongoing quality assurance support, and customized project support such as treatment planning system validation and HyperArc/Brainlab Elements implementation. Services are delivered by board-certified medical physicists via a hybrid on-site and remote model, and the firm has commissioned equipment at first-to-market sites including the world's first clinical Varian Edge (2014, Champalimaud Foundation) and the UK's first Halcyon (2017).

The firm operates a wholly owned European subsidiary, Medical Physics Services International Limited (MPSi), incorporated in 2008, which serves UK, Iberian, and Nordic clients directly. Customers are radiation oncology departments and medical physics teams at hospitals and freestanding clinics; named clients include Vanderbilt-Ingram Cancer Center, Norfolk and Norwich University Hospitals NHS, Guy's and St Thomas' Cancer Centre, Champalimaud Foundation, and the Portuguese Institute of Oncology. Engagements range from single-machine commissioning to multi-linac replacement programs (e.g., eight TrueBeams at Guy's and St Thomas', seven linacs at IPO Porto), with services typically sold on custom, project-based pricing under multi-year contracts.

MPS generates revenue exclusively through professional services fees, with no software, hardware, or product revenue. Distribution is direct to enterprise healthcare buyers, supported by referral networks within the medical physics community, conference participation (AAPM, ESTRO), and peer-reviewed publications. The ownership is closely held by the founder family, with Hans Christian Beyer, J.D., serving as COO and general counsel; the firm has no external investors, no disclosed funding rounds, and no M&A activity on record. Operating geographies span the US, UK, Portugal, Spain, Sweden, and additional European markets, delivered through MPS and MPSi.

Broad incumbents

• Elekta: Elekta is a major radiation therapy and radiosurgery equipment manufacturer (Elekta Versa HD, Elekta Unity, Gamma Knife). It is comparable to MPS as the other dominant linac vendor whose installed base requires independent commissioning and QA services similar to what MPS provides.
• Accuray: Accuray manufactures CyberKnife and TomoTherapy radiation therapy systems, both of which require specialized commissioning and clinical physics support. It is comparable to MPS as a radiation therapy equipment vendor whose platforms are adjacent to the Varian ecosystem MPS focuses on.
• Varian Medical Systems (Siemens Healthineers): Varian, now part of Siemens Healthineers, is the dominant linear accelerator manufacturer whose equipment MPS specializes in commissioning. It is comparable as both an indirect competitor (offering its own clinical applications and commissioning support) and the primary vendor ecosystem MPS depends on for project flow.

Direct peers

• Sun Nuclear (Mirion Medical): Sun Nuclear, now part of Mirion Medical, is a leading provider of QA hardware and software for radiation oncology. It is highly comparable to MPS because both serve the radiation therapy QA and commissioning workflow — Sun Nuclear on the equipment side and MPS on the independent commissioning services side — and frequently appear together in linac commissioning programs.
• IBA Dosimetry: IBA Dosimetry provides dosimetry equipment, phantoms, and software for radiation therapy QA and commissioning. Like MPS, it sells into the medical physics workflow supporting linear accelerator commissioning and ongoing QA programs at hospitals and cancer centers.
• Standard Imaging: Standard Imaging manufactures dosimetry and QA devices for radiation therapy and offers associated commissioning support. Like MPS, it operates in the linac commissioning and QA ecosystem for radiation oncology departments and is a natural adjacent/complementary peer in the same workflow.
• PTW (Physikalisch-Technische Werkstätten): PTW is a global dosimetry and QA solutions provider for radiation therapy, including detectors and software used during linac commissioning. It is comparable to MPS as both serve medical physicists performing acceptance testing, commissioning, and ongoing QA on radiation therapy equipment.
• Radiation Physics Inc. Radiation Physics Inc. is an independent medical physics consulting firm providing commissioning, QA, and clinical physics services to radiation oncology facilities. It is comparable to MPS as a similarly positioned niche consultancy serving hospitals and clinics with linac commissioning and ongoing physics support.
• Associates in Medical Physics: AIMP is an independent medical physics consulting group offering clinical physics support, commissioning, and QA services to radiation oncology providers. It is the closest direct competitor type to MPS — a specialized independent consultancy focused on medical physics services rather than equipment.

Emerging players

• Landauer (Mirion Medical): Landauer, now part of Mirion Medical, provides radiation dosimetry and monitoring services across medical and occupational settings. It is comparable to MPS as an adjacent player in the medical physics and radiation measurement ecosystem, with some overlap in radiation oncology QA services.
