What Sun Nuclear does

Sun Nuclear Corporation, founded in 1984 and headquartered in Melbourne, Florida, is a medical-device company that designs and manufactures radiation-therapy and diagnostic-imaging quality assurance hardware and software. It operates as a wholly-owned subsidiary of Mirion Medical within Mirion Technologies (Mirion employs approximately 3,200 people across 12 countries). The company serves more than 6,000 cancer centers worldwide, with 1,600+ clinical users on its flagship SunCHECK platform, and reports direct enterprise customers including Iridium Kankernetwerk, NYU Langone Health, Moffitt Cancer Center, Hamilton Medical Center, and Clatterbridge Cancer Centre.

The core technology stack centers on the SunCHECK Platform — a browser-based, integrated quality management application combining patient QA (PlanCHECK, DoseCHECK, pre-treatment QA, in-vivo monitoring) and machine QA workflows. Sun Nuclear's hardware portfolio relies on proprietary SunPoint diode detector technology embedded in products such as ArcCHECK (1,386 detectors), EDGE Detector, SunSILICON, and Daily QA devices; the portfolio also includes 3D water scanning systems (SunSCAN 3D), ion chambers, and an extensive phantom line for SRS/SBRT, MR-linac, motion-management, and CT imaging QA. Following the April 2025 acquisition of Oncospace, Sun Nuclear added AI-powered software: Plan AI (FDA 510(k) cleared, CE marked February 2026) for predictive treatment-plan quality, and Gateway for Pinnacle-to-modern TPS data conversion. Other recent launches include AdaptCHECK (adaptive radiotherapy QA for Varian Ethos), evrCAM (radiation-tolerant PTZ camera), and Daily QA 4 Pro.

Revenue is generated through four streams: capital-equipment hardware sales (detectors, phantoms, scanners), software licenses and subscriptions (SunCHECK, Plan AI, PlanIQ), professional services (SunDEPLOYS implementation, training, repair), and Health Physics Solutions (DMC 3000, RDS-Med). All products are sold via quote-based enterprise contracts — no public pricing — through a combination of direct field sales and a global authorized distributor network, augmented by event-driven GTM at AAPM, ESTRO, and the company's own annual QADS symposium.

Direct peers

• PTW Freiburg: PTW is a German-based direct competitor in radiation dosimetry, producing ion chambers, diode detectors, the OCTAVIUS 4D detector array, and Beamscan water phantoms used in radiation therapy QA. It competes directly with Sun Nuclear's detectors, water phantoms, and patient-specific QA offerings in Europe and globally.
• IBA Dosimetry: IBA Dosimetry, a division of IBA SA (Belgian), is one of the largest global manufacturers of radiation therapy QA equipment including ionization chambers, Blue Phantom water phantoms, and myQA patient QA software. It is a direct competitor in dosimetry hardware and QA software, serving the same cancer centers and radiation oncology departments worldwide.
• Modus Medical Devices: Modus Medical Devices (now including Standard Imaging) manufactures QA phantoms and detectors for radiation therapy, with deep overlap to Sun Nuclear's phantom and detector product lines (StereoPHAN, ArcCHECK equivalents). The combination creates a sizeable direct peer in independent radiation oncology QA hardware.
• Standard Imaging: Standard Imaging is a direct competitor in radiation therapy QA, manufacturing ionization chambers, electrometers, phantoms, and the QA-STEREOTYPE/CHECKMATE product lines. It competes head-to-head with Sun Nuclear in linac and patient-specific QA, and was acquired by Modus Medical in 2024, making it the closest US analog to Sun Nuclear's portfolio.
• CIRS (Computerized Imaging Reference Systems): CIRS manufactures tissue-equivalent phantoms and QA solutions for radiation therapy and diagnostic imaging, directly comparable to Sun Nuclear's Solid Water HE, StereoPHAN, and CT/MR phantom portfolio. It serves overlapping customers in radiation oncology and diagnostic imaging QA.

Emerging players

• RaySearch Laboratories: RaySearch develops the RayStation treatment planning system and RayCare oncology information system, with growing machine learning capabilities for automated planning. Sun Nuclear's Gateway converts patient data to RayStation and Plan AI provides external plan-quality assessment, creating both integration partnership and emerging competitive overlap in AI-driven treatment planning.

Broad incumbents

• Varian Medical Systems (Siemens Healthineers): Varian is the dominant radiation oncology delivery and treatment planning vendor (Eclipse, Halcyon, Ethos, TrueBeam) and an integration partner of Sun Nuclear. While Varian's QA capabilities are typically less specialized than Sun Nuclear's, its bundled approach and adaptive Ethos platform represent both a collaboration channel and a long-term competitive risk for independent QA vendors.
• Elekta: Elekta manufactures linear accelerators (Versa HD, Unity MR-linac), treatment planning systems (Monaco), and related oncology software. Sun Nuclear's Daily QA-MR and SciMoCa are explicitly designed for Elekta Unity environments, making Elekta both a critical integration partner and a broad incumbent that competes for QA budget allocation at cancer centers.
• Accuray: Accuray manufactures the CyberKnife and TomoTherapy/Radixact radiation therapy delivery systems. Sun Nuclear's StereoPHAN (with CyberKnife AQA inserts) and MotionCHECK 3D (for Radixact Synchrony) are explicitly designed for Accuray platforms, positioning it as a key QA partner while Accuray itself competes in the broader oncology capital equipment market.

Others

• Lap GmbH Laser Applications: Lap GmbH produces laser-based patient positioning systems and QA phantoms used in radiation oncology. It is an adjacent peer to Sun Nuclear's MotionCHECK 3D and Daily QA 4 Pro in the broader radiation therapy QA and positioning ecosystem, though focused on different physics (laser/optical vs. dosimetry).
