Direct peers

• Varian Medical Systems (Siemens Healthineers): Varian is the global market leader in linear accelerator (LINAC) radiation therapy systems, holding a dominant installed base. It is the most direct competitor to Accuray's Radixact and TomoTherapy platforms in image-guided and intensity-modulated radiation therapy, and was acquired by Siemens Healthineers in 2021.
• Elekta: Swedish-headquartered Elekta is the other global LINAC incumbent alongside Varian, offering competing image-guided radiation therapy and stereotactic radiosurgery systems. It directly competes with Accuray in hospitals and cancer centers worldwide, particularly in Europe and emerging markets.
• RaySearch Laboratories: RaySearch develops RayStation treatment planning and RayCare oncology information systems that integrate with multiple LINAC platforms including Accuray's CyberKnife and Radixact. It is both a partner (via iDMS integration) and a software competitor in the treatment planning ecosystem.

Emerging players

• Brainlab: Brainlab specializes in radiosurgery treatment planning software and neurosurgical navigation. While also an Accuray integration partner, it overlaps competitively in neuro-radiosurgery planning workflows where CyberKnife is also sold.
• ViewRay: ViewRay's MRIdian system combines MRI imaging with radiation therapy delivery, competing in the image-guided radiation therapy space with a differentiated real-time soft-tissue visualization approach. Targets similar adaptive radiotherapy use cases as Accuray's Stellar and Radixact platforms.
• Mevion Medical Systems: Mevion is a U.S.-based developer of compact proton therapy systems. While proton therapy is a different modality, it competes for the same hospital capital equipment budgets and advanced radiotherapy service-line expansion as Accuray's CyberKnife and Radixact.
• IntraOp Medical: IntraOp Medical manufactures the Mobetron, a mobile electron beam intraoperative radiation therapy system. It addresses a more specialized radiation oncology niche but competes with Accuray for advanced radiotherapy capital purchasing at comprehensive cancer centers.
• Sensus Healthcare: Sensus Healthcare develops superficial radiation therapy (SRT) systems primarily for skin cancer and keloid treatment. While not a direct LINAC competitor, it competes for radiation oncology capital dollars in dermatology and superficial treatment settings adjacent to Accuray's market.

Broad incumbents

• Hitachi (particle therapy systems): Hitachi's healthcare division offers proton and heavy ion therapy systems. While not a direct LINAC competitor, it competes with Accuray for advanced radiotherapy capital budget allocations at large academic medical centers.

Others

• C-RAD: C-RAD provides patient positioning, surface imaging, and motion management solutions for radiation therapy. It is both a technology partner with Accuray and an enabler of advanced radiotherapy workflows that complement Accuray's systems.
