IBA Quasar

What IBA Quasar does

IBA Quasar is a product brand of physical and software quality-assurance tools for radiation therapy, owned and operated by IBA Dosimetry GmbH, a subsidiary of publicly listed IBA Group (Euronext Brussels: IBA). The QUASAR line consists of advanced phantoms (patient and motion simulators) and reference software used by medical physicists to calibrate, align, and validate radiotherapy delivery and imaging systems, with particular depth in MR-guided radiotherapy (MR-Sim and MR-Linac), IGRT, motion management, IMRT, 3D dosimetry, and image distortion analysis for Gamma Knife platforms. Named SKUs include the Motion MR Platform, MRgRT Insight Phantom, MRI4D Motion Phantom, MRID3D, pRESP 2.0, Platform HD, Penta-Guide Phantom, and GRID3D Advantage.

The franchise serves hospitals, cancer clinics, and radiation therapy centers worldwide, with cited deployments across 3,000+ premier treatment centers and 10,000+ users in 125+ countries, supported by an enterprise field-sales model, the ICC International Competence Center training program, and QA-plus support services. Revenue mechanics are predominantly specialized hardware sales bundled with software and services to clinical buyers; no public pricing or per-unit economics is disclosed. The brand carries a registered QUASAR trademark in the EU, UK, and US, and operates under the broader IBA Dosimetry portfolio rather than as a standalone P&L.

Corporate context: IBA Quasar/Modus QA was founded in 2000 and is reported to be based in London, Canada (per firmographics), while the trademark and product operations sit with IBA Dosimetry GmbH. IBA Group posted record FY 2025 revenue of €620M and a record €1.6B order book, providing indirect read-across to demand conditions, but no segment-level figures for IBA Dosimetry or QUASAR specifically are disclosed in the source data.

Direct peers

• CIRS (Computerized Imaging Reference Systems): CIRS manufactures tissue-equivalent phantoms and QA tools used across radiation therapy and diagnostic imaging. Its phantoms and imaging QA products compete with QUASAR's geometric distortion, motion, and image QA phantoms.
• Sun Nuclear (Mirion Medical): Sun Nuclear is the closest direct competitor to QUASAR in radiation therapy quality assurance, offering phantoms, dosimetry, and patient QA software to medical physicists. Both vendors compete head-to-head for commissioning, machine QA, and patient QA budgets at treatment centers worldwide.
• Standard Imaging: Standard Imaging provides QA phantoms, electrometers, and software for radiation therapy. It overlaps with QUASAR in IMRT/VMAT QA, brachytherapy QA, and patient-specific QA delivered to medical physicists at treatment centers.
• PTW Dosimetry: PTW is a leading independent vendor of RT QA and dosimetry equipment, including ionization chambers, detectors, and phantoms. It competes directly with QUASAR in patient dosimetry, machine QA, and detector-based QA for photon and proton therapy.

Broad incumbents

• Varian (Siemens Healthineers): Varian, now part of Siemens Healthineers, is a major linac and radiation oncology software vendor. Its Eclipse, TrueBeam, and HyperSight ecosystem increasingly bundles QA tooling, making it a broad incumbent competing for QA budget at customer sites.
• Elekta: Elekta is a global radiation therapy and radiosurgery systems vendor (Elekta Unity MR-Linac, Versa HD, Gamma Knife). As an OEM, it competes with QUASAR by integrating QA workflows and commissioning services around its own linac platforms.
• Accuray: Accuray manufactures CyberKnife and TomoTherapy/Radixact systems and bundles QA tools for its robotic and helical delivery platforms. QUASAR explicitly supports Radixact and CyberKnife, positioning Accuray as both a partner and competitive channel.
• IBA Dosimetry: IBA Dosimetry is the parent product division that owns the QUASAR brand and offers a broader RT QA portfolio (including non-QUASAR products like myQA, MatriXX detectors). It is the immediate corporate parent and the wider portfolio against which QUASAR's offering is positioned.

Emerging players

• Fluke Biomedical / RaySafe: RaySafe (Fluke Biomedical) offers patient dose monitoring and real-time dosimetry solutions for radiation therapy and diagnostic imaging. Its patient dose monitoring line competes with QUASAR's diagnostic imaging and patient dose QA offerings.
• LAP (Laser Applications and Lasers): LAP specializes in patient positioning, laser alignment, and motion-enabling systems used in radiation therapy. It is adjacent to QUASAR's motion management and targeting QA portfolio and overlaps in QA workflows for SGRT and motion-guided RT.
